Malignant melanoma accounts for a small percentage of all skin cancers, but accounts for most deaths from skin cancer. Malignant melanoma starts in the melanocytes–cells that produce pigment in the skin. Malignant melanomas sometimes begin as an abnormal mole that then turns cancerous. This cancer may spread quickly. Malignant melanoma most often appears on fair-skinned men and women, but people with all skin types may be affected. Melanoma is a disease of the skin in which cancer starts in the melanocytes, the cells that produce color in the skin from a pigment known as melanin. Melanoma usually occurs in adults, but it may occasionally be found in children and adolescents. Melanoma may also be called cutaneous melanoma or malignant melanoma. Melanoma is an uncommon, but aggressive, form of skin cancer. Melanoma is a more serious type of cancer than the more common basal cell cancer and squamous cell cancer. Although the incidence of melanoma is lower than other types of skin cancer, it has the highest death rate and is responsible for a majority of all deaths from skin cancer.
