People with hairy buttocks tell fortune.

There is a hairy black birthmark on a man's ass for fortune telling.

Melanoma often grows in the face, forehead, neck, chest, lower limbs and other parts of the body, with the head, face, neck and chest being the most ugly. The cell nest of nevus is located in epidermis and dermis, and the skin is protuberant or papillary with rough surface. Some of them have little hair, while others are thicker and darker than ordinary hair. Some people have this kind of mole at birth, some people have it in childhood, and it gradually expands with age. Be more careful about moles that grow on parts of your body that are easy to rub or get hurt, and be careful that they don't become murderers who ruin your face. If the mole grows rapidly, the color becomes lighter or darker and brighter, local itching, burning pain or pain, hair loss and redness on the surface, visible bloodshot, or ulceration and scabbing, and even a long-lasting ulcer is formed. The nearby lymph nodes are swollen, or there are some satellite-like small moles around the big moles, which all indicate that the moles have a tendency to become malignant.
