Squamous cell carcinoma is a common skin cancer that arises from the squamous cells, which form most of the top layer of the skin. Like basal cell carcinoma, it is most commonly found in sun-exposed sites, but can arise in any location of the body. Squamous cell carcinoma has a low risk of spreading to other areas of the body, however certain cases carry more risk. The treatment is similar to the treatment of basal cell carcinoma.
Squamous cell carcinoma is a type of nonmelanoma skin cancer.
