Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer and one of the most common cancers overall in the United States. [3] An estimated 3.5 million cases of nonmelanoma skin cancers were diagnosed in the United States in 2006; of those, approximately 80% were basal cell carcinoma (BCC) and 20% were cSCC.

Despite increased knowledge and public education regarding the causes of skin cancer and modes of prevention, the incidence of cSCC continues to rise worldwide. This increasing incidence is likely multifactorial; the speculated causes for the rise include an aging population, improved detection, an increased use of tanning beds, and environmental factors, such as depletion of the ozone layer.
