Squamous cell carcinoma is a form of skin cancer. It is the second most common form of skin cancer.

The cancer develops in the uppermost layer of skin cells. Squamous cell carcinoma usually grows slowly. It is rarely fatal if treated early. However, the cancer can be lethal if it spreads beyond the skin.

Cancer occurs when cells in the body divide without control or order. Eventually these uncontrolled cells form a growth or tumor. The growths invade and take over nearby tissue. It is not clear exactly what causes these problems in the cells but is probably a combination of genetics and environment.
