Squamous cell carcinoma

Squamous cell carcinoma is the second most common type of skin cancer. It occurs in chronically sun damaged skin such as the face, arms, and back of the hands. Unlike basal cell carcinomas, a small percentage of squamous cell carcinoma can potentially metastasize or spread internally, and thus become a serious health risk. When limited to the skin, squamous cell carcinomas can be effectively treated and cured. They commonly appear as thick scaly new growths or open sores.
