The nonmelanoma skin cancers (NMSC) are the most common human cancer type. More than half of all cancers diagnosed in the United States are NMSC. In the year 2003, more than 1.3 million new cases of NMSC will be diagnosed.1 One in 5 Americans born in 2003 will be diagnosed with skin cancer in their lifetime. Recent publications and articles in the lay press have labeled nonmelanoma NMSC as today's epidemic. The incidence of NMSC has been rising since the 1960s at 4% to 8% per year.3 Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) account for 96% of new cases of NMSC. The remaining 4% consists of many other types of NMSC, but given their low incidence, discussion of these lesions is beyond the scope of this chapter.
