Melanoma is a type of skin cancer. It is the less common form of skin cancer but it can be more serious because it is more likely to spread to other parts of the body.
Melanoma arises from the type of cells that give moles their dark colors. These cells can be found in the skin, eyes, digestive system, nail beds, or lymph nodes. Although melanoma is most common in the skin it may also arise in these other areas.
Treatment for melanoma depends on how early it is detected, or if the melanoma has spread.

Cancer occurs when cells in the body divide without control or order. Eventually these uncontrolled cells form a growth or tumor. The term cancer refers to malignant growths. These growths invade nearby tissues and spread to other parts of the body. It is not clear exactly what causes these problems in the cells but is probably a combination of genetics and environment.
