Melanoma is a type of skin cancer that starts in the melanocytes. It is not as common as basal cell or squamous cell skin cancer, but it is much more serious. See the patient information summary on melanoma for information on the treatment of that type of cancer. Skin cancer is more common in people with light colored skin who have spent a lot of time in the sunlight. Skin cancer can occur anywhere on the body, but it is most common in places that have been exposed to more sunlight, such as the face, neck, hands, and arms.
Skin cancer can look many different ways.
The most common sign of skin cancer is a change on the skin, such as a growth or a sore that won't heal. Sometimes there may be a small lump. This lump can be smooth, shiny and waxy looking, or it can be red or reddish brown. Skin cancer may also appear as a flat red spot that is rough or scaly. Not all changes in the skin are cancer, but a doctor should be seen if changes in the skin are noticed.
