Most skin cancers develop on areas of the skin that get years of sun exposure, like the face, neck, ears, forearms, hands, and trunk. Basal cell carcinomas and squamous cell carcinomas are the most common, but melanomas are the deadliest.
Basal cell carcinoma (BCC) looks like a flesh-colored, pearl-like bump, or pinkish patch of skin. BCC frequently develops in people who have light skin, but it can occur in people with dark skin. With early treatment, this type of cancer can be cured. Left untreated, BCC can cause bleeding and severe damage, which can be disfiguring.
Squamous cell carcinoma (SCC) can look like a red scaly patch, raised, firm bump, or a sore that heals and re-opens. People who have light skin are most likely to develop SCC, but it can develop in dark-skinned people, especially those who have scarring. With early detection and proper treatment, SCC has a high cure rate. Left untreated, SCC also can be disfiguring. In rare cases, untreated SCC can spread to other areas of the body and can be deadly.
Melanoma may develop in a mole or it may appear as a new, dark spot. Sometimes melanoma contains shades of red, blue or white. When found early, melanoma often can be cured. Left untreated, melanoma can spread to the other areas of the body and can be deadly.
