Why birthmarks grow

A newborn child can have no birthmarks at all, but with time they certainly appear. The number of nevi can increase throughout life. Why is this happening?

The natural growth of moles can be the reasontoo long exposure to the sun, various dermatological diseases and changes in the hormonal background. Pathological neoplasms appear on the basis of malignant degeneration of a normal birthmark. Properly identify the nature of a nevi can only a dermatologist or an oncologist.

Accidental damage to the birthmark

• 
  after a trauma, the mole hurts and itches;


• 
  the skin around the mole is inflamed;


• 
  On the place of the torn stain there are small nodules;


• 
  the stain increases in size;


• 
  the skin in place of the torn birthmark changes color;


• 
  for no apparent reason, bleeding is resumed on the damaged area of ​​the skin.
