What is Melanoma?
Melanoma is a type of cancer in which cancer cells form in skin cells called melanocytes. Melanocytes are the cells that produce melanin, which is what gives our skin, hair and eyes their colour. While melanoma starts on the skin, it can spread into other tissues and parts of the body.
