These types of skin cancer are called nonmelanoma skin cancer . 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. 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 your body, but it is most common in places that have been exposed to more sunlight, such as your 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 your skin are cancer, but you should see your doctor if you notice changes in your skin.
