Medically known as pigmented nevus, it is a skin manifestation caused by the increase of melanocytes in epidermis and dermis. It can appear anywhere in the body, at birth or the day after tomorrow. Some can be benign all their lives, and some can be malignant.

Moles on the body, especially on the face, have various common names among the people, such as Beauty Mole, Happiness Mole, Wealth Mole, Tears Mole, Delicious Mole and Foucault Mole.

In fact, these are all different aesthetics formed by different times, different regions, different nationalities and different folk cultures, which are endowed with different meanings. Some fortune-telling feng shui masters regard these moles as the basis of good or bad luck, and everyone's right can be regarded as entertainment. Don't believe it.

Although moles have nothing to do with bad luck, they do have benign and malignant points. We usually say that moles are benign, and when moles worsen, they can develop into malignant melanoma.

Healthy people can usually find 10 ~ 20 moles on the skin. If these moles do not hinder the appearance, there is no need for treatment. A few moles on rubbing parts, such as pigmented moles on palms, armpits, perineum and soles, may induce cancer due to repeated rubbing or stimulation. It is recommended to go to the hospital dermatology department and treat with ultra-pulse laser.

Intradermal nevus refers to the pigment has reached the dermis, slightly raised, and some nevus will grow hair. Mixed mole is somewhere in between. The color of moles can be black, brown, brown and blue-black. The possibility of malignant transformation of nevus has nothing to do with the type of nevus, but is closely related to the characteristics of nevus.

Nevus with malignant tendency have five characteristics. First of all, they are asymmetrical in shape and irregular in appearance. Second, the edge of the mole is blurred and uneven; Thirdly, nevus progresses rapidly in a short time; For example, three-month growth 1-2 times; Fourth, the diameter of the mole is greater than 5 mm; Fifth, the color of the mole is uneven.
