The moles themselves are safe and do not pose a threat to health. However, medium and large nevi can turn into malignant tumors such as melanoma. Anton Ivanov, chief physician of the Mamma clinic, oncologist, oncosurgeon and chemotherapy specialist, told socialbites.ca.
“Nevis is the result of the accumulation of neocyte cells in a single place. These are mutated melanocytes (special skin cells that produce the pigment melanin). Nevus vary in size: small ones occupy up to 1.5 mm, medium ones – up to 10 mm, and large ones – more than 10 mm. As a rule, medium and large moles have a tendency to turn into melanoma,” said Ivanov.
According to him, the transformation of nevi into melanoma can begin without any apparent reason.
“If you notice a sudden change in color and texture (decrease or increase in pigmentation), a strong growth in diameter or height of the neoplasm, thickening, redness and peeling of the mole, you should immediately consult a dermatologist,” the oncologist explained.
Malignant processes in a mole may also be indicated by nevus bleeding, the appearance of pain, itching or burning sensations at the site of the neoplasm, as well as enlargement of regional lymph nodes.
“During the visit to the doctor, it is necessary to give the most detailed information: when the mole appeared, how the nevus appeared last time (are there any signs of degeneration). “Treatment of a nevus, as a rule, occurs by removal by cryodestruction, electrocoagulation, laser or scalpel,” concluded the expert.
