Squamous-cell carcinoma or squamous-cell cancer (SCC or SqCC) is a cancer of a kind of epithelial cell, the squamous cell.These cells are the main part of the epidermis of the skin, and this cancer is one of the major forms of skin cancer. Unlike basal-cell carcinoma (BCC), squamous-cell carcinoma (SCC) has a substantial risk of metastasis. 2  Risk of metastasis is higher in SCC arising in scars, on the lower lips or mucosa, and occurring in immunosuppressed patients.
Squamous cell carcinoma, or SCC, is a common form of skin cancer. This type of skin cancer is a tumor that affects the middle layer of the skin. Squamous cells are cells that compose most of the epidermis. An abnormal growth of these cells is known as a squamous cell carcinoma. How does it form? Squamous cell cancer results when cells in the middle part of the skin start to change. The changes may begin in normal skin or in skin that has been injured or inflamed. Most skin cancers occur on skin that is regularly exposed to sunlight or other ultraviolet radiation. It is most often seen in those over age 50. Over 90% of skin cancers occur on areas of the skin that are regularly exposed to sunlight or other ultraviolet radiation; this is considered the primary cause of all skin cancers.
