Melanoma is a cancer that initiates in a certain type of skin cell. It begins in the melanocytes. Most of the melanoma cells do produce melanin hence melanoma tumors are usually black or brown in color, while some lack melanin and occur pink, tan, or even white.
It can develop on any part of the skin of the body, but most likely to start on the trunk (chest and back) in men and on the legs of women.
