Squamous Cell Carcinoma (SCC)
With more than 250,000 new cases each year, Squamous cell carcinoma is the second most common skin cancer in the U.S. SCC is a cancer that forms in the outer layer of the skin and usually appears as either a growing tumor, non-healing ulcer or a crusted, scaly patch with a red, inflamed base. SCC often develops from small, sandpaper-like growths called actinic keratoses.
Squamous cell carcinomas are most common on sun-exposed areas of the skin, such as the face, neck, arms, scalp, ears and the backs of the hands, but can occur anywhere on the body. SCC is more common in middle-aged and elderly people, especially those with fair skin.
