MedlinePlus, the Medical Encyclopedia provided by the National Library of Medicine, U.S. National Institutes of Health, provides basic information on squamous cell carcinoma — incluiding its medical definition, causes, risks, symptoms, diagnosis, treatment, prognosis, and prevention.
Squamous cell carcinoma is the second most common form of skin cancer, after basal cell carcinoma.
It can spread faster than basal cell carcinoma, but still may be relatively slow growing. It can metastasize (spread to other parts of the body).
Non-melanoma skin cancers have a relatively high rate of cure, if treated early. The principal cause of squamous cell carcinoma is exposure to sunlight.
