2nd most common form of nonmelanoma skin cancer after basal cell carcinoma.  When caught and treated early, it rarely causes further problems.  Untreated, SCC can grow large or metastasize, causing serious complications

the most common type of nonmelanoma skin cancer, is a cancerous tumor of the basal layer of the epidermis, or hair follicles.  Basal cell carcinoma is commonly caused by overexposure to sunlight.  Although basal cell carcinomas rarely invade distant structures of the body, they tend to recur- especially those that are larger than 2cm.
