Skin cancer. Close-up of a malignant melanoma (skin cancer) on the thigh of an 86-year-old female patient. A malignant melanoma is a type of skin cancer that arises from melanocytes, the cells that produce melanin, the pigment that gives skin its colour. The main cause of melanoma is exposure to ultraviolet radiation in sunlight. It is an aggressive cancer that often spreads (metastasizes) to other parts of the body. Treatment is with surgical excision of the melanoma.
