This skin cancer begins in the squamous cells, which are also found in the skin's upper layer. More than 200,000 cases are reported each year in the United States. SCC may appear as a crusted or scaly area of skin with a red, inflamed base that resembles a growing bump, a non-healing ulcer or a crusted patch of skin. While it usually appears on areas of the body that frequently are exposed to the sun, SCC can develop anywhere, including areas that never typically receive sunlight. SCC requires early treatment to prevent it from causing damage to surrounding body features and from spreading to other areas of the body.
