Most skin cancers are not melanoma (nonmelanoma). The most common nonmelanoma skin cancers are basal cell carcinoma and squamous cell carcinoma, which start in either the basal cells or squamous cells located at the base of the outer layer of skin (epidermis). The majority of nonmelanoma skin cancers develop on sun-exposed areas, resulting in formation of abnormal skin cells. With rare exceptions, most nonmelanoma skin cancers don't spread to other parts of the body and are curable if detected and treated early.
