What do “suspicious” moles look like?
Moles, birthmarks, nevi – all these are the names of benign formations on the skin that can be congenital or appear during a person’s life. Moles can be located everywhere, even on the mucous membranes, have a different shape and color. Moles themselves do not affect health in any way, and their treatment is not required. An exception may be very large nevi, which cause a person certain inconvenience or disfigure his appearance. In this case, they are recommended to be removed. The danger of moles lies in the possibility of their degeneration into a malignant formation.
Which moles are dangerous
But not all nevi are prone to malignancy. In medicine, moles are divided into melanomas and melanomas. The first group includes five varieties of nevi.
A giant mole is considered very dangerous – it degenerates into a malignant tumor in 50% of cases. This is a huge tuberous formation that can occupy a significant part of the body, such as the back or chest. In appearance, it resembles a wart of gray or brown color. A giant mole grows throughout life.
The border mole is a dark or black evenly colored small spot up to 1 cm in diameter with a smooth, dry surface. It does not grow and does not change color, solar radiation does not act on it. As a rule, the border nevus is located on the soles, palms, in the intimate zone. It degenerates into a malignant formation in 10% of cases.
Blue nevus is a small (usually about 1 cm) dense rounded mole of blue, grayish or black-blue color, towering above the skin and well defined. It is localized on the head and neck, hands, feet, buttocks. As a rule, such moles are single, that is, a person has it in the singular. Malignant rarely.
Nevus Ota is a fairly large birthmark of a bluish-brown or bluish-gray color, located on the face, auricle, oral mucosa in the cheek area. It has an uneven shape and uneven coloring. Often congenital or appears during the first 20 years, mainly in representatives of the Mongoloid race. It rarely degenerates into melanoma.
Dubreuil melanosis is a small spot from light brown to black in irregular shape with well-defined borders. The spot is colored unevenly and sometimes resembles a black blot on a brown background. It develops mainly on the face, most often in people with fair skin, prone to sun exposure, usually in women after 50-55 years. Growing slowly. It is considered a precancerous condition and degenerates into melanoma, according to various sources, in 45-75% of cases.
What contributes to the degeneration of moles into melanoma
Risk factors for malignancy of moles include:
intense ultraviolet radiation;
What should alert you?
Unfortunately, few people pay attention to their moles, and as a result, a person comes to the doctor when a harmless birthmark degenerated into a malignant tumor. In order to detect dangerous symptoms of mole degeneration in time, they should be regularly examined. Here are the signs that should alert and force to see a doctor.
Color change. If the mole has changed color or dots, lines of a different shade have appeared on it, this may indicate its degeneration.
Contour change. A dangerous sign is blurred, fuzzy spot borders.
Asymmetry. Usually, nevi, with the exception of congenital spots, are symmetrical. The fact that the mole has become asymmetric should alert.
Enlarged moles. Normally, a mole can grow during puberty of a teenager. If in an adult, nevus suddenly increases significantly in size, you should visit an oncologist-dermatologist.
Other pathological changes. Any changes that appear: crusts, cracks, peeling, itching, tingling, bleeding, the appearance of a red rim around a mole, etc. – this is an occasion to consult a specialist.
Remember that it is impossible to diagnose yourself. And even more you can’t self-medicate – you can hurt yourself, and very much. The specialist will determine the nature of the education, quickly, painlessly and with high accuracy and recommend treatment.
If necessary, a suspicious mole is removed and a histological analysis is performed to determine its nature.
