Cancer that begins in cells that form the epidermis (outer layer of the skin). It usually occurs on areas of the skin that have been exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. These areas include the face, ears, lower lip, neck, arms, or back of the hands. It may also occur on areas of the skin that have been burned or exposed to chemicals or radiation. Squamous cell skin cancer may appear as a firm red bump, a scaly red patch, an open sore, or a wart that may crust or bleed easily. Squamous cell skin cancer that has not spread can usually be cured. Also called cutaneous squamous cell carcinoma and squamous cell carcinoma of the skin.
