Is it good to have 15 moles on your body? The appearance of moles on the body of an adult: causes and features

Is it good or bad when many moles appear on the body?

Let's answer this exciting question and figure out whether this is a cause for concern.

Most people have no more than 40 moles on their body, but there are also those whose skin is simply strewn with small and fairly large pigmented formations.

Is it worth paying attention to them? A large number of tumors on the skin - is it good or bad?

Let's find out when there are a lot of moles on the body, what it means, why they appear and in what cases you need to contact a specialist.

Causes of a large number of nevi

Many moles on the body appear due to many factors, including: various diseases, and the influence of external stimuli.

The main causes of nevi:

1. solar radiation. During exposure ultraviolet rays on the skin, the activity of melanocytes is activated, which are responsible for the transformation of melanin in skin tissues - the formation of moles. This is why it appears on the body greatest number moles in places that are constantly exposed to UV radiation: on the arms, face, shoulders and legs;
2. hormonal disbalance. It is not difficult to remember that during puberty in adolescence or during pregnancy the largest number of moles appeared. This physiological process, in which the hormonal status changes dramatically, provoking changes in the skin tissues in the form of the appearance of new nevi. Their number may increase after severe stress, during menopause or after hormonal therapy;
3. external factors. These include exposure to X-rays, long-term non-healing skin lesions and insect bites, which can become a gateway to infection. In the future, moles are likely to appear in this place.

From birth

When a child has many moles on his body, then in most cases it is worth talking about hereditary predisposition To advanced education pigmented skin cells.

This process is especially accelerated when such a child spends a lot of time in the sun, receiving more and more portions of sunlight.

More often, nevi are localized in children on the back, arms, legs and chest.

Reds

If red nevi appear on the body in large numbers, a person should not worry too much: they will never degenerate into melanoma.

An abundance of red growths on the skin occurs for the following reasons:

• pathology of the circulatory system: deformation and proliferation of blood vessels, veins, arteries;
• disruptions in the functioning of the cardiovascular system (in particular, diseases of the pancreas) and gastrointestinal tract;
• problems with lipid metabolism;
• liver diseases;
• cell pigmentation disorders;
• abuse of solarium.

Hanging

If a person begins to develop a lot hanging moles, then this is a sure sign of his infection with the papilloma virus, which provoked fast growth nevi on the stalk.

Their danger lies in the risk of injury, so you need to get rid of them.

But first the patient is prescribed a test for papillomavirus and subsequently drug treatment, aimed specifically at combating the provocateur.

In addition to the described reason for the appearance of hanging nevi, other provoking factors are also considered:

• genetic predisposition to the formation of moles from the border cells between the dermis and epidermis;
• hormonal surges when hanging nevi appear after childbirth or during puberty;
• UV irradiation, if a person has neoplasms of this nature after prolonged tanning in the scorching sun.

Hanging moles are most often localized on the face, neck and chest, but can appear in other places and even on the genitals.

What is the danger

Therefore, such people should regularly monitor the condition of each neoplasm, self-examining them and visiting an oncodermatologist for preventive purposes.

If nevi on the body do not secrete fluid, do not become inflamed, do not change size or color, or itch, then even a large number of them does not pose any danger.

In this case, the difficulty is only in observing the moles, and not in their number. Indeed, among most neoplasms, it is sometimes difficult to see one that has signs of degeneration, especially when it is located on the back of a man or woman. And melanoma can form both in a person with 50 nevi, and in the owner of 5 moles.

• You need to be especially careful with your skin in places where the most tumors are located: on the neck, shoulders, face, chest. You should avoid rubbing or injuring the skin in these areas of the body.
• Nevi that form on the palms, soles, and arms of a woman or man are especially dangerous. They are constantly rubbed and can become damaged, which increases the risk of developing melanoma.

In order to prevent degeneration, such neoplasms must be removed.

Signs

When a person has a large number of nevi, he must know the main 6 signs of a dangerous neoplasm.

For convenience, they are grouped according to the following scheme:

• A – asymmetry: If you visually draw a horizontal or vertical line through the middle of the nevus, the two halves should be identical. In case of their asymmetry, melanoma is suspected;
• K – edge: jagged, protruding or uneven edge indicates the degeneration of a mole. In a healthy neoplasm they are even and smooth;
• K – bleeding: is a sign of malignancy of the nevus. Any discharge from a mole is also considered a sign of degeneration;
• O – color: must have a uniform structure without stains or foreign inclusions;
• P – size: the larger it is, the higher the risk of tumor degeneration;
• D – dynamics: any change with a nevus can be considered a sign of melanoma.

What to do, if Can at least one sign from the test described above be applied to a mole?

Urgently seek advice from an oncodermatologist who will conduct an appropriate examination of the nevus, take an analysis if necessary and determine further actions in relation to the disturbing neoplasm. Most likely it will be deleted.

What to do

There is no need to panic right away, because a very large number of moles is not a sign of melanoma, but the need for a careful and attentive attitude towards your body.

• Daily examination of all neoplasms should become an integral part of the lives of such people.
• A trip to an oncodermatologist would be a good idea: only a specialist can identify initial stage transforming even one of many small moles.

If the doctor does not find any suspicious growths on your body, then in the future you should adhere to simple rules:

1. regular self-examination of all small and large nevi for dynamic changes;
2. wearing loose clothing made from natural fabrics;
3. using soft sponges for washing in the shower or bath;
4. limiting prolonged exposure to direct sunlight;
5. application sunscreens with an SPF factor above 50.

If a large number of nevi appear in places increased risk rubbing or injury (on the back, chest, palms, feet), they need to be removed in a suitable way, after consulting with an oncodermatologist.

Questions and answers

Many red moles have appeared on the body, what does this mean?

It is impossible to say for sure why such changes occur in the skin.

After all, this may be preceded by various reasons, such as pathology of capillaries, malfunction of the gastrointestinal tract, cardiovascular system, and lipid metabolism disorders.

Therefore, to establish the real reason Patients are recommended to undergo a comprehensive examination.

New nevi appeared during pregnancy

This fact is predictable, since during pregnancy a hormonal surge occurs.

• As a result, active pigmentation of cells begins with melanin accumulated in the skin tissues and many new moles appear or old ones increase in size.
• Nevi appear on the stomach, face, chest and other parts of the body; they can be either flat or convex, red and hanging.

Is it possible to sunbathe if there are a large number of birthmarks on the body?

Nowadays it is fashionable to have a bronze skin color, but not every visitor to the beach or solarium is interested in whether it is possible to sunbathe if there are many nevi on the body.

You can sunbathe, but only before 10 am and after 6 pm; being under the open sun at this time will not harm the skin and the moles on it.

The rest of the time, UV radiation provokes increased production melanocytes produce melanin, which accumulates in the skin tissue and causes the appearance of more and more moles.

It is known that solar radiation can influence a nevus to degenerate into melanoma.

Therefore, when tanning, you must follow the rules of being in the sun, using sunscreen.

If small

In this way the skin responds to strong sunburn when melanin is produced with greater force.

When there is an excess of it, a “rash” of small black spots occurs on the skin.

What does this mean and should we be afraid of it? Doctors classify this skin reaction as protective and do not consider it dangerous.

If small nevi are light in color, then there is a possibility that they will disappear on their own.

• Some people argue that multiple appearances of small moles are signs that a person has committed a significant act in life.
• What interpretation means is up to each individual to decide. It's more important to keep track of each new mole on your body.

Prevention measures

Answering the question of why a person develops a large number of skin tumors, many doctors agree that their occurrence is initially embedded in DNA from an early age.

Therefore, in most cases it is impossible to radically influence their number.

But still, there are other reasons for the appearance of moles, which are attributed to external factors.

Therefore, it is possible to determine the main measures to prevent the multiple occurrence of neoplasms, which include:

1. limiting long-term exposure to solar radiation;
2. absence of injuries and damage to the skin, careful attitude towards oneself;
3. wearing loose clothing without pressing or rubbing elements;
4. use of sunscreens;
5. control for general condition health;
6. support of hormonal balance.

Particular attention should be paid to the last item on the list: before planning a pregnancy or the onset of puberty, you should consult an endocrinologist.

Video: “The whole truth about moles!”

Mole or nevus is a benign pigment formation on the skin that is congenital or appears during life. Moles can be different in shape, size and color: flat in the form of a speck or convex like a pea, dotted or large sizes, from light flesh to dark Brown. Under the influence of unfavorable external agents (excessive amounts of ultraviolet radiation, nevus injury, etc.), a mole may develop malignancy– melanoma.

Mole or nevus is a benign pigment formation on the skin that is congenital or appears during life. Moles can be different in shape, size and color: flat in the form of a speck or convex, like a pea, dotted or large in size, from light flesh to dark brown. Under the influence of unfavorable external agents (excessive amounts of ultraviolet radiation, nevus injury, etc.), a malignant neoplasm - melanoma - can develop from a mole.

Congenital nevi

The causes of moles (nevi) can be divided into two large groups: congenital and acquired.

Congenital nevi are a defect embryonic development, which is based on a disruption in the process of migration of melanoblast cells (precursors of melanocyte pigment cells) from the neuroectodermal tube into the skin. The accumulation of these pigment cells in the skin leads to the formation of moles (nevi).

Moles are not visible on the body of newborns, but they begin to appear in the first years of life.

Depending on the size, moles are divided into small (d - from 0.5 to 1.5 cm), medium (d - from 1.5 to 10 cm) and large (with a diameter of more than 10 cm). Large nevi that occupy individual anatomical areas of the body (for example, the buttock) are called giant nevi.

Small moles are not dangerous in terms of degeneration into a malignant tumor, but medium, large and especially giant ones are much more susceptible to malignancy. Possibility of malignant transformation giant nevi in melanoma ranges from 10 to 50%. People with large moles on their bodies should be under the supervision of a dermatologist and oncologist. Such nevi should not be exposed ultraviolet irradiation, and in some cases it is better to remove it for preventive purposes.

Throughout life, the number of moles constantly changes. They can appear in new areas of the body, change their contours, color, and relief. Therefore, moles should be constantly monitored independently and shown to a doctor.

The appearance of moles during life is genetically determined: if the parents had moles, they will most likely be passed on to the child.

A significant increase in the number of moles is associated with endocrine changes in the body and occurs in adolescence and during pregnancy. The appearance of new moles is provoked skin infections(acne, irritation, rash, etc.), causing inflammatory changes in the epidermis. But the most powerful catalyst for the growth and increase in the number of moles is excessive sun exposure of the skin. Therefore, the owners significant amount moles, you should limit yourself to visiting the solarium and staying under the sun.

U infants nevi occur in 4-10% of cases, and by the age of 15-16 years they are already present in more than 90% of people. With age, the number of moles decreases. So, at the age of 20-25, their number on the body is on average 40; by the age of 80-85, most people do not have a single mole. IN mature age There are 15-20 nevi on the human body.

Depending on the location in the skin, acquired nevi are divided into intradermal (clusters of melanocytes are located deep in the dermal layer of the skin), epidermal (clusters of cells are formed in the epidermis - the upper layer of the skin) and mixed or borderline (clusters of melanocytes are located on the border of the epidermis and dermis).

Acquired intradermal and epidermal moles usually look like peas. Borderline nevus, in most cases, looks like a flat, brownish spot, flush with the skin.

It is vitally important to recognize the malignancy of a mole in time and distinguish it from a benign nevus. Timely diagnosis precise definition stage of melanoma development is the key to successful treatment.

In a conversation with the patient, it is clarified when the pigment formation arose (whether it is congenital or acquired), whether the type of nevus, its size, shape, color has changed. If changes occurred, what caused them (trauma, burns, scratching, removal attempts), how long ago the changes were noticed. It also turns out whether the nevus was treated and what plan this treatment was. During the examination of a mole or spot, its size, color, shape, and other visible characteristics are specified.

It is visually impossible to distinguish benign and malignant neoplasms with a sufficient degree of certainty, for more accurate diagnosis necessary special studies. It should be remembered that a biopsy (partial removal of a nevus) for histological examination is strictly unacceptable.

It has been established that any traumatic impact (mechanical, chemical, radiation) can cause degeneration of some types of melanoma-dangerous nevi, especially borderline ones, into malignant form. Therefore, biopsy, as well as such types cosmetic treatment such as electrocoagulation, cryotherapy (cryodestruction), removal of moles using chemical substances pose a risk of developing a malignant tumor.

Material for histological examination of nevi is obtained by taking a smear from the surface of the neoplasm if there are cracks and bleeding on it. The next day you can already have finished result examination of tissue, which is carried out under a microscope.

Such a study should be carried out only in specialized oncological institutions, where it is possible immediately after receiving the results under local anesthesia completely remove the neoplasm (with 3-5 mm margins from the edges) for further histological examination. In a few days the result will be ready.

Currently appeared new method diagnostics – epiluminescent microscopy. The study is carried out using an optical device with artificial illumination (dermatoscope) directly on the surface of the body. A few drops are applied to the pigment formation vegetable oil to create the effect of epiluminescence (an oil medium appears between the object of study and the dermatoscope), then the device is placed at the site of study. This research method does not damage the nevus and is the most accurate in determining the structure of the pigmented neoplasm.

Method computer diagnostics is also one of the advanced research methods. Using a digital video camera, an image of the pigment formation is recorded and stored in the computer memory. A special computer program processes the received data, compares it with a database and issues an accurate conclusion.

The disadvantage of computer diagnostics and epiluminescence microscopy is their high cost, which prevents them from widespread in our country.

The question of removing moles arises before the patient in two cases: when the tumors are a cosmetic problem, and also in the case of oncological indications. The method of removal will depend on the category of indications. In both cases, the decision remains with the specialist.

Cosmetic indications

To solve a cosmetic problem, remove moles and birthmarks can be done surgically, using liquid nitrogen(cryodestruction), using electric current high frequency (electrocoagulation), using a laser or radiosurgery.

The surgical method is traditional and is especially suitable in the case of removal of deep or extensive nevus. Disadvantage surgical method there are noticeable marks after the operation, because the mole has to be removed along with the adjacent skin; according to oncological requirements, the diameter of the excised surface should be 3-5 cm, depending on the location of the nevus.

Cryodestruction is a method of destroying tissue by cold (liquid nitrogen at ultra-low temperatures). The mole shrinks, forming a dry scab (crust) and reliably protects the wound from infection. Over time, healthy tissue grows underneath it. Cryodestruction is used to remove nevi that are at the same level as the skin. Sometimes the effect of nitrogen extends to healthy tissues or does not completely destroy pathologically altered ones. In the latter case, a repeat session is required.

The electrocoagulation method involves thermal exposure to high-frequency current on the tissue around the lesion to be removed. After electrocoagulation, the mole should be sent to histological analysis. After removal of the nevus, the wound heals under a crust, with the formation of a faint scar.

The most effective method today is to remove skin lesions using a laser. It is often used to remove moles on the face and exposed parts of the body. The advantages of the laser are its small diameter and precise depth of exposure, and the preservation of surrounding tissue. A slight crust after laser surgery protects the wound from infection and scar formation. After removing small moles, no trace remains; with more extensive lesions, an area of ​​depigmentation sometimes appears.

Radiosurgery is a non-contact method of tissue excision using a surgitron apparatus (radio knife) using radio waves. Widely used in cosmetology, used to remove benign and malignant formations. It combines tissue cutting, hemostatic and disinfecting effects and does not leave postoperative scars.

Oncological indications

Nevi suspected of malignant degeneration are subject to complete surgical excision within healthy tissue and subsequent histological examination.

IN Lately There is a trend towards a significant increase in the number of skin melanoma diseases worldwide, especially in women young. In men, melanoma is more often localized on the back, and in women - on the lower limbs. The statistics on the incidence of skin melanoma in Russia is also disappointing; it amounts to four cases per 100 thousand population. Growing through all layers of skin, tumor cells with the flow of blood and lymph they are carried throughout the body, forming distant metastases(secondary tumor foci) in the lungs, liver, brain. The mortality rate for skin melanoma reaches 50%. You can prevent the development of skin melanoma by following these recommendations:

1. If possible, avoid exposure to the sun during the period of its highest activity from 11 a.m. to 5 p.m. In summer, even in cloudy weather, 85% of ultraviolet rays penetrate the skin.
2. It should be borne in mind that the ultraviolet radiation absorbed by the skin is doubled when reflected from sand, water and even snow.
3. Sunscreens (creams, lotions, sprays) perfectly protect the skin from sunburn, but do not guarantee protection against the development of melanoma.
4. Tanning in a solarium also provokes the development of skin cancer, and it can be especially harmful to women under the age of 28.
5. You should regularly and carefully monitor existing and newly appearing moles. If their condition or quantity changes, an emergency consultation with an oncologist or dermatologist is necessary.

Causes of moles

Moles, or, as experts also call them, nevi, can be a congenital or congenital malformation of the skin. Such moles arise due to large cluster in the skin there are melanocytes, that is, skin cells filled with melanin. It is worth noting that the formation of moles on the body is genetically based. If your parents had moles, then you, most likely, cannot do without them.

Also characteristic feature moles become a change in their number over time. A mole may appear on a completely new area of ​​your skin, and an old one may change its color, contour or relief. Thus, it will be extremely useful to periodically monitor your moles. And at the first sign of a change, you should immediately consult a doctor.

Moles can appear according to various reasons, but most common reasons The reasons why moles form on the body are as follows:

• Endocrine restructuring of the body, which is observed in adolescents, as well as in women during pregnancy. This factor is one of the main factors for the appearance of moles.
• The most various diseases skin: rash, irritation, pimples or redness. All this can cause the appearance of new moles, also affecting inflammatory processes epidermis.
• Increased skin insolation is also an almost ideal catalyst for the growth of moles. It leads not only to an increase in their number, but also to an increase in the size of individual moles. Thus, for someone who already suffers from a large number of moles all over the body, it would be advisable to avoid exposure to the hot sun or visiting a solarium.

Types of moles

In general, you can count several types of moles at once. Take the classification by color - moles can be white, red or completely black. Appearance on the skin brown moles Shouldn't be a cause for concern at all. Many moles can also change their color or size over time. There are:

1. Hemangiomas, or vascular moles. They appear on the skin in the form of hanging nodules. On the other hand, in rare cases they may be completely flat and red or pink in color.
2. Not vascular moles. This type looks most like warts. They can be very arbitrary in size, from small to quite large. In addition, the color of such formations can also vary widely.
3. The most common are lentigos, or flat moles. They are formed by those melanocytes that lie almost at the very surface of the skin. It is noteworthy that tanning does not in any way affect such moles. They will not darken or change size when exposed to the sun. Lentigines are similar in color to freckles.
4. Convex moles. Melanocytes are also responsible for their appearance, but these are those that lie deep in the skin. Most often, such moles are up to a centimeter in diameter and have hair. The surface can be either smooth or bumpy.
5. Blue moles. Most often, such moles rise somewhat above the surface of the skin, often appearing as a formation in the shape of a hemisphere. Moles can be dense, most often lack hairline. The size of each mole of this type can reach two centimeters in diameter, and the most common places of appearance are the face, buttocks and limbs.
6. Pigmented giant moles. Most often, such moles are congenital. They can also increase in size as a person grows. The surface of such moles is flat and can occupy a significant area on the surface of the body. Most often, their color ranges from grayish and brown to completely black.

In most cases, moles can appear on any part of the human body and in a variety of shapes. It is not uncommon, for example, for moles to form a triangle.

Reasons for enlarging moles

Of course, in light of all of the above, many people are interested in how moles form and why they increase in size. It is worth noting that the main factor responsible for the appearance of new moles is skin insolation. An injured mole may also noticeably increase in size, which subsequently degenerates into a malignant tumor. Thus, it is very important to periodically examine the condition of your moles in order to notice signs of such degeneration in time.

ATTENTION. As soon as you notice such symptoms, you should immediately consult a doctor. Removing a mole with your own hands is strictly prohibited.

The point is not that you will most likely encounter a situation where a scar has formed after removing a mole, but that by taking such a step you will greatly harm your health. So, if you notice any changes in your mole, you should see a doctor. We can recommend this one to you experienced specialist, as Elena Vladimirovna Salyamkina.

Are moles dangerous?

Unlike the vast majority of other skin formations, a mole attracts minimal attention and only in rare cases becomes a reason for a visit to a specialist. As already mentioned, you should not ignore even the slightest changes in the color or size of your moles. Bleeding, cracks in a mole, or a large number of new moles will also be a signal for a visit to the doctor.

In particular, the first symptom of melanoma is a sharp darkening of the mole. A timely and correct diagnosis is half the success of treating this disease. It is simply vital to identify a malignant nevus in a timely manner and distinguish it from a benign one. A diagnosis made on time will be the key to successful treatment.

Mole removal

So you've decided to remove your mole. First of all, you should immediately and completely refuse the services of beauty salons, and moreover, from various methods of self-medication for grandma's recipes. The result of such treatment, if any, will certainly not be positive. In this case (as in most others), you can entrust your health only to specialists with the appropriate medical education and work experience.

First, you will need to go to a dermatologist who will perform a procedure called dermatoscopy. This procedure is non-invasive and completely painless. At this stage, the specialist will consider whether your mole should be removed at all. If it turns out to be of poor quality, then he will immediately be sent to a surgeon, who will begin to remove it. Today, there are several methods for removing moles: surgical, radio wave, laser, using liquid nitrogen or electrocoagulation.

Remember that mole removal cannot be carried out in cases where you are susceptible to various allergic diseases, during acute respiratory infections or during feverish. Mole removal is also contraindicated for people with herpes infection.

Moles on the body are increasing: why are they growing?!

Moles can be congenital or acquired. The first type of nevi is formed on the skin due to a disruption in the movement of special cells - melanoblasts, for which the final stopping point should be epithelial tissue embryo. Accumulated melanoblasts are the main cause of mole formation in infants.

Reasons for the growth of moles

Over the following years, the number of elements in a person changes upward. Why do moles grow?

Experts identify the following as the most common factors contributing to the increase in birthmarks:

• diseases of the skin of an infectious nature, causing inflammatory changes in tissues;
• endocrine changes in the body inherent in the periods of puberty and pregnancy;
• excess ultraviolet radiation received in a solarium or during prolonged exposure to the sun;
• injury to the element by friction against clothing or during shaving.

Not every person is able to notice that a mole is growing on him. The enlargement process can occur very slowly, causing the element to grow by only 2 mm per year. And this is difficult to notice with the naked eye.

A sharp increase in nevus size signals the possible start of irreversible processes in the body. In second place in terms of pathological changes It is worth compacting the pigmented spot. The remaining areas are distributed between changes in the color and structure of the surface of the nodule, itching and bleeding.

A dermatologist or oncologist will be able to figure out whether the growth of a mole really indicates the development of melanoma. Therefore, regarding any atypical changes in the tumor, you should consult with specialists. Self-medication in this case is unacceptable and dangerous.

Features of large moles

Birthmarks, or large moles on the body, can also become injured and degenerate into melanoma. They require increased attention, because any damage is fraught with malignancy.

Some people complain that nevi get in the way normal life and rush to get rid of them. Is it worth surgically excising the pigmented lesion? Doctors consider such a patient’s desire to be justified, since in certain areas of the body large elements are constantly at risk of injury or cause all sorts of inconvenience or aesthetic discomfort.

When moles on the body increase, this indicates an excess of melanin and its accumulation at the location of the elements. Initially benign neoplasms arise precisely because of the accumulation of skin pigment – ​​melanin – under the dermis. And although the substance is inherently dark in color, the colors of moles can vary significantly and even merge with the body due to the shade matching it.

The most common moles of this color are:

1. black;
2. gray;
3. dark brown;
4. natural bodily tonality.

If the mole has significantly increased in size, then it is time to visit a dermatologist. This situation is dangerous due to the formation of a malignant tumor on the skin, and anything could provoke it - from rubbing with a tight or synthetic item to exposure to solar radiation.

A pathological nevus differs from a healthy mole not only in its large size, but also in its uneven color and irregular edges. It is recommended to record all changes and provide the collected information to the doctor. If reliable information is available, it will be easier for him to figure out how long ago the pathological mechanism was started.

A pigment spot is called large if its size is more than 10 cm. Small moles are characterized by a size of 0.5 to 1.5 cm, medium nevi - from 1.5 to 10 cm.

Is the growth of moles in children dangerous?

Small skin elements do not pose a threat to the baby's health. But if parents notice that a mole is growing on their child, they should show him to the doctor as soon as possible. After a visual examination and receiving test results, the specialist will give advice and prescribe adequate treatment.

According to statistics, approximately 40% of all registered cases of large spots on children's body end with degeneration into a tumor. As long as babies have small moles and do not change in size, there is no need to worry. You just need to monitor them and prevent injury.

Simple preventive measures for parents are:

• checking the symmetry of large elements;
• tracking the growth of nevi;
• observation of color and structure;
• comparison of contours;
• observation by a dermatologist or oncologist (one consultation per year is sufficient).

If new formations appear frequently in a child, and subsequently moles on the body grow so that their diameter exceeds 5 mm, it is necessary to contact the clinic. It is also worth rushing to the doctor if the baby inadvertently tore off a nevus, because often injury to the element serves as an impetus for the launch of destructive processes in the fragile body. Protruding nodules are especially at risk of injury in children.

Instead of an afterword

As you understand, when a mole grows, the answer to the question “what to do” begins with observing the element. Having assessed its color, shape, size and structure, mentally compare them with previously available indicators. Record the new values.

If you find the changes insignificant, repeat the study after a while. Be sure to pay attention to the contours of the nevus - their jaggedness is a sign of melanoma. If a mole rapidly increases in size, itches, peels or bleeds, hurry to see a doctor.

At his discretion, the specialist will offer laser evaporation of the problematic element or radio wave removal. The techniques are absolutely safe, atraumatic and do not leave scars or scars. Surgical excision of the nevus is resorted to in advanced cases, when, along with the growth, other clinical manifestations melanoma.

kozhnyi.ru >Black moles on the body photo

During pregnancy. The material promotes awareness of the safety of moles for a number of reasons and encourages contacting a doctor if moles begin to behave unusually.

Period of occurrence

Moles appear on the human body from birth, although initially a person is born without any pigment spots at all. Most of them occur during adolescence, when the formation of the human body occurs. They can appear and disappear, manifest themselves in very different ways, grow or die, but every inexplicable behavior of a mole should be perceived as a danger, and a person who notices moles on the body or their change is simply obliged to consult a doctor in order to avoid more serious problems. than itching or peeling of a mole.

All moles can be radically different from each other and be different color: brown, skin colors, black, pink, white and even purple, and also be different shapes and structures: angular, flat, lumpy and sharp, or generally subcutaneous and almost invisible.

Causes

Moles can appear on a person’s body at any time in his life, despite the fact that the main period of their birth occurs before the age of 25 years. Moles can appear anywhere and anyhow, and they can also disappear. Let's look at the various reasons for the appearance of moles:

The appearance of moles in humans may be due to hereditary information embedded in DNA. Hence the name moles, since they are often inherited and appear in the same place as in older relatives.

Emergence from the sun

One of the most effective influences on the appearance and growth of moles is solar radiation. Under its influence, the human body produces quite intensively a certain substance - melanin. It forms the basis of moles. An excess of melanin, which is perfectly produced by the body under ultraviolet rays, forms huge colonies of new moles on the surface of the skin, which is already a risk factor. Each mole increased quantity exposure to the sun can transform into a tumor, and a malignant one.

Moles due to injury and some viruses

In the same time great amount Doctors are confident that moles appear due to radiation and x-rays, which every person receives at one time or another. There is another opinion viral infection and insect bites that for a long time leave their marks on human skin. With any of the above effects on the body, a process can be started during which melanocytes group and find their way to the surface of the skin.

Alternative medicine opinion

The appearance of moles on the body is caused by the release of internal energy. Energy accumulates at the site of inflammation, concentrates over time and provokes the appearance of age spots and moles on the skin.

Hormonal surges

It affects the release and formation of melanin, which in turn pigments the mole. strong effect a hormone secreted by the pituitary gland. For this reason, any hormonal surge in the human body can lead to multiple births of new moles. This may explain moles during pregnancy or during puberty. Such bursts can lead not only to the birth of moles, but also to their disappearance.

How to prevent the occurrence

After reading everything written above and understanding the causes of moles on the body, you can try to prevent the increase in the number of moles. To achieve this, according to experts, the most important thing is to refrain from increased consumption. solar radiation, that is, sunbathing less during the solar zenith and minimizing visits to the solarium, this will be enough for a start.

New moles

The appearance of new moles on the body is often explained by the influence unfavorable factors on the body. It could be severe stress, hormonal surge, radiation exposure and unfavorable ecological situation. If the appearance of new moles bothers you precisely because of their number, then you should spend less time in the sun and protect your skin with the help of special creams, lotions and protective filters. Often moles are normal behavior body, until they begin to bother the owner and cause physical or aesthetic discomfort. It is worth paying attention to the growth of the mole, the increase in the number of moles, peeling, itching and other factors of a sharp change in the structure and size of moles on the body.

Variety of birthmarks in children

The appearance of red or any other moles on a child’s body can be caused by a variety of for various reasons and be both dangerous and safe. As a rule, only moles that belong to one of the groups appear on the skin of babies:

• Light brown or skin colored moles that are not too noticeable most often remain for life. If their number increases, then there is cause for concern and you should consult a doctor for advice.
• Birthmarks are dark in color and vary in shape. They can appear on any part of the body. They are also harmless and can last a lifetime, but if there are any changes in shape, color or quantity, you must consult a doctor.
• Red moles on the child's face, back of the head and neck. in children is explained by expansion small vessels during childbirth. Single manifestations may remain for a long time, but identical and mirror-image red moles may disappear within the next year.
• Mongoloid spot. Most often it appears in children with dark skin and is located on the child’s buttocks or lower back. The blue-purple marking does not require any treatment and most often disappears by about 13-15 years of age.
• Hemangiomas. They can be convex or flat.

Convex moles are a clear indicator that moles form during pregnancy and appear during this period, and sometimes immediately after the birth of the child. They do not bring any negative sensations and can disappear within a few years, but if convex hemangiomas are located in risk areas, where they can be damaged, then it is advisable to cure them. It is necessary to begin treatment at a young age, since convex hemengiomas, if they have not disappeared, can grow, and by the age of 15 they can turn into a huge spot. And finally, flat formations - they are harmless and do not grow over the years, and therefore it is not at all necessary to remove them.

Doctors' warnings

All doctors insist on the same thing. Removing moles is not at all a mandatory process, since they themselves do not cause any harm, except moles on the face, which can spoil a person’s appearance, or those moles that are located on dangerous areas of the body: on the neck, on the eyelids, on the toes and so on. These moles can be easily damaged and cause some anxiety. In addition, the appearance of moles on the body most often does not cause any harm to the body, except in cases where you notice signs of transformation of the mole, which are the first reason for visiting a doctor:

• compaction and sudden change in the size of the mole;
• change in color of the mole, sharp pigmentation in dark color;
• cracks in the mole, peeling, bleeding;
• inflammation of a mole or its areola;
• disruption of the structure of the skin pattern on the surface of moles.

Having considered all the warnings of doctors, the reasons for the appearance of moles, we can conclude that if a mole does not behave unusually and does not cause discomfort, then the only reason for its removal may be an aesthetic and emotional reason and, if this must happen, then we recommend laser removal of moles or removal with nitrogen.

The procedures are virtually painless and leave no visible marks on the skin, but should only be performed by qualified professionals.

Every person has moles. Some have a lot of them, and some even small speck difficult to find. Sometimes a person may notice that many moles have appeared on the body in places where they were not there before. What to do in this case? Why do nevi appear on the body? Is this a health risk or not? We will examine these and other questions in this article.

Moles are otherwise called nevi. They have always received close attention from dermatologists, as they accompany us throughout our lives. However, few can say anything specific about nevi. It’s interesting, but a newborn baby has no moles on his body at all. The exception is birthmarks, but that's a different topic. The first nevi begin to form after the child reaches 6 months. This process continues constantly due to predisposing factors.

Moles are benign formations. Depending on the method of their formation, they are divided into 2 types:

1. Vascular. They are formed from the capillaries of the lymphatic and circulatory systems. Painted in shades of red.
2. Not vascular. They are formed from melanocyte cells, where melanin accumulates. They range in color from brown to black.

They can be convex in shape, for example, papillomas, or flat. Moles can form on any part of the body. In general they are not dangerous.

Causes of moles

Many people are interested in the question, why do many small and large moles appear on the body? Indeed, in some cases it may not look very beautiful, especially if they are located on the face, chest and neck. Among the reasons for the appearance of new nevi are:

1. Ultraviolet abuse. You should not spend too much time under the sun, as well as in the solarium (they especially like sunbathing women).
2. Heredity. It has been reliably established that a large number of moles on the body are inherited through generations.
3. Hormonal changes ( puberty, pregnancy period, illness endocrine system, severe stress, etc.).
4. Radioactive radiation. There is an opinion that frequent use mobile phone and computer promotes the growth of melanin in the human body, but this statement has not been proven.
5. Skin injury and insect bites. If the damaged area of ​​skin is not treated correctly, then an environment favorable for infectious processes. This factor can also provoke the formation of a large number of nevi.

Is there any danger

Is there a threat human health if a lot of moles begin to appear over a period of time a short time, what does it mean?

First of all, you shouldn’t give in to panic, but you shouldn’t let the situation take its course. The appearance of many nevi on the skin does not mean their malignant degeneration into melanoma - skin cancer. The real danger is present if moles begin to change. A person who has a large number of moles should know 6 main signs of a neoplasm that threatens health. For ease of perception, they are grouped by CHORD scheme:

1. A– asymmetry. If you draw a visual line through the middle of the nevus, then the 2 halves should be identical. If there is asymmetry, cancer is suspected.
2. TO- edge. Degeneration is indicated by uneven, protruding or jagged edges. A healthy mole should have smooth and even edges.
3. TO– bleeding. This is a sign of a malignant tumor. This also includes any discharge from the nevus.
4. ABOUT- coloring. It should be uniform, without inclusions or extraneous stains.
5. R- size. The larger the mole, the more risk her rebirth.
6. D– dynamics. Almost any change that occurs with a nevus can be considered a symptom of melanoma.

If you experience any of the above symptoms, you should urgently visit an oncodermatologist. If there is no such specialist, then an oncologist. The doctor will conduct an examination, take tests and decide what needs to be done with the disturbing tumor.

What to do if a lot of moles appear

The transformation of moles into oncology often occurs due to a careless attitude towards them. For example, in case of accidental injury, rubbing, removal of hairs growing from a nevus, etc.

If you have a large number of moles, it is important to know what to do. Preventive measures to prevent the appearance of melanoma include:

• regular examination of all neoplasms for their dynamic changes;
• using soft sponges for washing in the shower;
• using a certain soap that is sold in a pharmacy (the doctor will tell you which one);
• skin treatment with special moisturizing ointments and creams;
• taking appropriate vitamin preparations;
• wearing only loose clothing made of breathable and natural fabrics;
• limiting exposure to the sun;
• use of sunscreens with an SPF factor above 50.

You need to be especially careful with the skin in those places where there are the most moles. It is necessary to avoid injury or rubbing of the skin in these areas. And, of course, a visit to an oncodermatologist would not be amiss. Only he can detect malignant transformation on initial stage.

It is also worth noting that you should absolutely not remove moles yourself or do it in dubious beauty salons. In case of incompetent removal, bleeding may begin, which can lead to blood poisoning. Examination and treatment of moles should only be trusted to a doctor.

To remove moles or not

The issue of removing problematic moles must be approached responsibly. You can think about this only after a thorough examination by a doctor. Potentially dangerous nevi are removed as quickly as possible. It is also necessary to eliminate moles located in traumatic places (back, chest, neck) and visible areas (face, arms, legs).

There are many ways to remove moles. Most optimal doctor selects based on each specific case. Please note that you cannot go for mole removal without consulting a doctor. The main methods for removing nevi include:

1. Laser removal. The mole is removed using a laser beam, which burns out the problem area. Before this, the patient is given local anesthesia.
2. Electrocoagulation. Nevus is burned out using electric current low frequencies. Quite a traumatic way.
3. Radio wave technique. This is a hardware technique. After anesthesia, the mole is irradiated with high-frequency waves.
4. Surgical excision. Used to remove only large moles with high probability melanoma development. The nevus is excised with a portion of the skin.

After removal, the histological material must be sent for examination to identify malignant cells in it.

If many small moles appear, there is no need to worry - they are not so dangerous. Their appearance can be caused by various reasons, which were mentioned above. The only thing you need to do is to regularly examine your moles. If there is the slightest change, you should immediately consult a doctor.

A person who has many nevi on his body is prone to their degeneration. Therefore, he must follow all preventive measures to prevent melanoma.

There is a belief that those with a large number of moles are happy people. However, if there are large moles on a person’s body, then this attracts attention. Especially if they are on the face. There is always a risk that such skin formations can cause malignant tumors. Large moles should be constantly monitored, noting their size and color.

A mole is a pigmented formation on human skin, which is an accumulation of melanin. Moles come in different shades of brown. There are also red ones, which are formed as a result of growth blood vessels. In medicine, moles are called nevi.

It is a well-known medical fact: nevi appear on the body during a person’s life, because at birth such formations are absent in all people. Their number is growing every year. But some people may have several of them, while others have their entire body covered with them. The main period when nevi appear on the human body is puberty. However, in adulthood their number can increase sharply and they can change size, shape and color. Various changes in the human body, especially hormonal ones, lead to the appearance of moles. In women, an increase in their number is most often observed during pregnancy and menopause.

They greatly influence the appearance of nevi Sun rays. After a holiday at sea, new formations appear on the body and back. Some of them then disappear, while others accompany a person throughout his life.

Large red nevi appear in places where subcutaneous blood vessels develop abnormally. Over time, they increase and reach the top layer of the skin. Such a mole can also appear in places where blood vessels develop normally, but their concentration is significant. They compress the tissue, creating a nevus. Large red nevi on the body occur if the lipid metabolism, the work of the large intestine or pancreas.

Large hanging nevi occur due to activation of the papilloma virus in the human body. Nevi are also inherited. Very often you can notice that different generations families in the same place have almost identical nevi.

Moles have different color scheme, which depends on the amount of melanin. Nevi do not have roots, unlike warts, but the depth of their growth into the skin varies. Moles on the body are considered benign formations and do not pose a threat to the human body.

Varieties

May be in various places, have different sizes, colors and shapes. Nevi are classified as follows:

1. Sutton moles- colored formations on the skin surrounded by colorless rings.
2. Setton moles- colored or colorless spots. They are located in the form of clusters that range in size from 1 to 2 cm.
3. Becker's moles- are dark, warty spots that appear during puberty. Throughout a person’s life, they constantly grow, reaching a size of 20-30 cm in diameter. Over time, hair appears on the spots. Typically occur on the back, chest, buttocks and legs. Mostly occur in men.
4. Pigmentless nevi- white or pale pink spots that are located close to each other.
5. - appear at an early age and resemble warts, but do not have roots. Over the years they can increase and reach a diameter of 2-3 cm.
6. Sebaceous moles- arise in infancy on the neck, temples, under the hair. Recommended for removal.
7. Unna's birthmark- a large pigmented spot resembling a bird's beak. Localized on the forehead or back of the head. It forms in the first days of a child’s life, but disappears completely after a few years.
8. Fire nevi- pigment spots that appear in the first days of life. Over the years they increase and become more distinct.
9. - appear due to pathological proliferation of subcutaneous capillaries. They can reach large sizes - up to 5 cm.
10. New cell moles- appear at birth and are a flat, one-color spot. They may increase over the years. Popularly called birthmarks.
11. Blue nevi- are dangerous to health because they can develop into melanoma. Usually they have a diameter of 0.5-3 cm.
12. Melanocintar nevi- flat formations round shape Brown color. Often appear during pregnancy and with prolonged exposure to the sun. Quite dangerous because they can start the development process at any moment cancer.
13. Papillomatous moles- are caused by the papilloma virus. They have a bumpy surface. They can occur throughout the body, but most often appear on the scalp under the hair. They can have a diameter of up to 2 cm.
14. Fibroepithelial nevi- raised skin of red, pink and brown colors.

Are they dangerous?

Nevi that have a diameter of more than 3 cm are considered large. Many people believe that large moles are dangerous. But it is not so. All nevi carry danger and the possibility of transforming into melanoma, but nevi are much safer than warts because they do not have roots. Large moles on the body are just areas of the skin stained with melanin.

If, then it is definitely safe, since with the development of skin cancer, hair falls out. Try to examine the moles on your body at least once a month, noting their color, size and shape.

Causes of rebirth

To transform nevi into melanoma, an irritant is needed that will trigger this process. Large nevi are more dangerous in this aspect because they have large area defeats.

The most important and dangerous factor that can trigger the development of melanoma is ultraviolet rays. Each person has their own safety threshold at which their skin can withstand sun exposure. However, people whose bodies are heavily covered with moles should be wary of tanning. No sunscreen will protect nevi from exposure to ultraviolet radiation.

Pregnant women are prohibited from sunbathing. During pregnancy, a woman's body begins hormonal changes, which causes the appearance of moles. Newly formed nevi do not yet have immunity to ultraviolet rays and can easily degenerate into melanoma, because during pregnancy the immune system women are weakened.

Melanoma can also be caused by injuries to nevi. This can be not only a bruise or a cut, but also constant rubbing of moles with bras, bag straps, combs, etc.

Symptoms of melanoma development

The symptoms of melanoma are quite difficult to notice, but you should be wary if the mole:

• began to increase rapidly or became convex;
• itches or hurts when pressed or spontaneously;
• bleeding;
• changed color or became multi-colored;
• inflamed;
• cracked;
• began to darken or lighten;
• black dots appear around or in the middle of the mole;
• began to lose the clarity of the contour.

Diagnostics

If a person notices changes in the nevus, then it is necessary to contact an oncodermatologist, who will conduct an examination and refer him for the necessary tests. At the appointment, the doctor will first conduct a survey regarding the period of appearance of the mole, its modification, etc. Next, an external examination of the mole will be carried out to determine its color, shape, size and presence of hairs. After the examination, the doctor will order tests, which include:

• a smear from the surface of the nevus - the structure is studied under a microscope;
• fluorescence microscopy - the nevus is examined under a special microscope directly on the human body;
• diagnostics using a computer - digital image of a mole using special program compared with the database; after analysis, the program produces a result with a description of the treatment; this procedure is quite expensive;
• laboratory tests - a nevus particle is tested for melanoma using oncotesters.

How to distinguish melanoma from a normal mole?

IN modern medicine There are 5 factors that help determine melanoma:

1. Asymmetry. A healthy mole, conditionally divided in the middle, should have two similar parts.
2. Color. With the development of melanoma, the mole has a heterogeneous color with different shades.
3. Size. When it degenerates into melanoma, the nevus begins to enlarge.
4. The edges. As melanoma develops, the edges of the mole blur and become ragged.
5. Dynamics of change. When observed, it may change size, color, shape, and bleed.

Treatment

Many people do not like moles from an aesthetic point of view. Sometimes they appear on the face or in places that are constantly injured (scalp when combing, female breast when wearing a bra, etc.). Treatment of nevi (non-melanoma) involves their removal from the skin.

Modern medicine offers several methods that will quickly get rid of moles:

• Surgical method. Used to remove large moles. By using surgical instrument excised upper layer epidermis with the possibility of skin transplantation;
• Cryodestruction. Nevi are removed using liquid nitrogen, which freezes the nevus tissue, turning it into a dry crust;
• Electrocoagulation. Moles are removed using high frequency current, which kills the tissue. This method is suitable for removing large moles;
• Radiosurgical method. Using a special radio knife, the nevus is excised without damaging adjacent tissues. The wound is simultaneously disinfected and cauterized to stop bleeding;
• Laser removal. This is the most effective method mole removal, which allows you to remove large nevi. Melanin is burned out using a laser. A colorless spot remains, which eventually merges with the skin.

Prevention

People who have large moles or many small ones on their body are advised to adhere to the following rules:

• Avoid visiting the solarium.
• Avoid sunbathing or sunbathe before 11 a.m. and after 4 p.m. Use suntan creams with increased level sun protection.
• Wear hats.
• Do not expose large moles to ultraviolet rays.
• In summer, protect your body with clothing. Try to wear light and light clothing.
• Do not use cosmetics and washing powders irritating to the skin.
• Wear sunglasses.
• Eat right and support your immune system.
• Periodically examine moles on the body, paying attention Special attention large nevi.

Let's sum it up

Large moles are not very dangerous if they are treated correctly. Dermatologists do not recommend removing them unless they pose a danger and do not interfere with a person’s life. Despite the development of medicine, nevi are not well studied today. It is not yet clear why nevi appear in residents of the north who constantly go to warm clothes. At all times, a person with an unusual mole was considered to be marked by the forces of good or evil. People believe that the number of nevi on the body equals the number of happy events that await a person in life. However, you should always remember that every mole is a time bomb that may not work, but can be launched at any moment. Therefore, we need to periodically examine the moles of our body.

A large number of nevi on the body is not a reason to sound the alarm and feel bad about yourself. It is much worse if several old moles begin to undergo metamorphoses: changes in color, shape, volume. In our article we will discuss the reason for the formation of such reincarnations, as well as their consequences.

Why are there many moles on the human body? on the body? Reasons for their formation can be quite varied. As a rule, such neoplasms appear in children, but they do not occur in newborns. After the first year of life, the number of small, light and inconspicuous spots increases, and, after a while, they become more rich shade, already clearly reminding us of familiar moles.

The vast majority of people have about 40 such marks. If their number is less than forty, then this is already a rarity. According to statistics, only 10% of people on the globe have less than 25 nevi on their body. No more than 5% of people are carriers of an abnormally large number of marks on the skin.

The reason for the formation of the spot is ultraviolet. Over time, as a result of growth, young cells produce melanin in excess of normal, which leads to discoloration.

In a large number of countries, nevi are considered a sign of good luck and happiness. During the research, scientists found that if there are a lot of moles on the body, then people age much more slowly and have more strong immunity, and:

Nevi on the back

A lot of moles on the back does not foretell any dangers. Undesirable changes in the structure of the nevus are indicated by changes in its shape and color. In this case, the number of nevi on the body does not play any role at all. People who are carriers of a large number of age spots are only advised to carefully monitor them and, in case of any changes, immediately consult a specialist.

Are new moles appearing - a cause for concern?

If each of your marks has been with you for a long time, then there is absolutely no reason to worry. If a lot of new nevi began to appear in as soon as possible, you should immediately consult a doctor. It is best to start your examination by going to a therapist, and he, based on his observations, will give you a referral to an oncologist or endocrinologist. First of all, referral to a doctor will depend on the concurrent symptoms detected by your doctor. Usually , the formation of new marks is provoked the following factors:

It is also worth noting that a person develops new nevi, possibly in large numbers, in adolescence, during pregnancy or menopause.

If there are many small and flat moles on your body, this means that you do not need to fight them, they do not pose any harm or threat. As for red moles, they are just as harmless. Red moles represent modified cells of blood vessels and disappear as imperceptibly as they appear. Why are there so many moles of this type on the body? And all because your body is prone to rosacea.

As for large, voluminous and pigment spots, they can pose a great danger. High risk of injury significantly increases the risk of a mole degenerating into a malignant formation. Cancer affecting the skin is extremely dangerous disease and you can calculate it by carefully observing such moles. The most pronounced and dangerous are the following symptoms:

1. Modification of shape;
2. Change of shade;
3. The pain is usually throbbing;
4. Discharge of ichor or blood.

The vast majority of doctors strongly recommend removing such moles to reduce the risk of developing melanoma in the future. This procedure is safe, but it is worth noting that not every mole can be removed; all cases are individual.

Child and nevi

If, then in the vast majority of cases this indicates a hereditary predisposition to the excessive formation of pigmented epidermal cells.

In particular, this process becomes very fast when the child is exposed to direct sunlight for a long time.

As a rule, nevi in ​​a child are localized in the areas of the back, arms, legs and chest.

Prevention

If you or your baby has a lot of spots on his body, then deleting them all is pointless and useless. In such cases, it is more advisable to observe the following preventive measures:

• Minimize or eliminate trips to the solarium;
• Do not expose the skin to direct sunlight;
• Regularly use high-quality sunscreens;
• Avoid injuring the formations and do not pull out hair growing through them.

Summarizing all of the above, I would like to add that moles are not a reason to be sad or panic. If you are attentive to your health, monitor the condition of your skin, visit your doctor in a timely manner, worry and take everything necessary measures when physiological changes your body, then no diseases will overtake you! Love yourself, respect and value your health, and it will repay you in a long and happy life no diseases!
