Melanoma begins in the cells (melanocytes) that make the pigment that colours your skin. It is a serious form of skin cancer that usually starts in unmarked, normal skin. But it can start in a mole or birthmark.
When melanocytes grow out of control, they can spread from the epidermis, which is the upper layer of skin, down into the dermis. Melanoma can spread rapidly to other parts of the body. Early diagnosis is important, since treatment works best when melanoma is found early.
