Dangerous moles

Birthmarks are almost all, some have more, some less. But do not think that if you have too many of these natural marks on your body and face, then the risk of melanoma, or skin cancer - is higher. Dangerous birthmarks, as a rule, develop gradually and only with confluence of certain factors. What exactly - you will learn from this article.

Which birthmarks are considered dangerous?

To understand which moles are dangerous, and which are not, you should carefully study all the nevi on the body. The nevus is the scientific name of a benign tumor that appears on the skin and produces a pigment melatonin. This is the familiar birthmarks to us from the point of view of medicine! They can be convex and flat, black and almost colorless, but the nature of the cells in all these cases is the same - skin tissue. This fact makes it possible to make significant distinctions between warts, in which the virus origin, red convex formations on the skin, which are a plexus of blood vessels and rough areas of the skin, which are a mutated corneous layer. Reborn in a malignant tumor can only moles! Of course, if other growths on the skin are interfering with you, they can also be removed.

The main signs of dangerous birthmarks are easy to remember:

• there was an itch;
• the shape or size has changed;
• the edge became uneven;
• there were uncomfortable sensations, tingling, pain;
• hairs fell out.

How dangerous moles look like, and what birthmarks are dangerous and cause melanoma, you will not tell any doctor. The fact is that visually potentially "bad" neoplasm does not stand out particularly. But nevertheless there are a number of factors which allows to bring a birthmark in candidates for close observation:

• the size is more than 5-7 mm;
• heterogeneous color;
• blood vessels visible on the body of a mole;
• congestion of 3-4 moles at one point;
• the absence of hair follicles in place of the birthmark.

What should I do to protect myself?

For those who have more than 10 large nevi on the body, it will be useful to get a skin passport. This medical document records all neoplasms and dermis spots, and allows you to track dangerous changes in time. In this case, it will be recommended to remove the birthmark . Without this procedure, it is impossible to say whether it is benign or already malignant. Biopsy samples from a living birthmark lead to cancer mutations in 80% of cases.

But do not be afraid if the doctor offers to get rid of a suspicious nevus: in this case it is better to be safe, the probability of developing melanoma is still extremely small. The most common skin cancer occurs in people who are often exposed to sunburn. If you are not one of them, the excitement is in vain.
