Basal Cell Carcinoma and Its Treatment

Janku Filip

More than 3.5 million skin cancers are diagnosed in more than two million Americans annually, making it the most common form of cancer in this country. Basal cell carcinoma (BCC) is the most common cancer in the United States with an estimated annual incidence of 0.5%. BCC is generally thought to affect men and women equally. Overall, the age-adjusted incidence of basal cell carcinoma per 100,000 persons was 25.9 for women and 20.9 for men; however, one analysis shows the incidence of BCC has increased significantly among women only. Compared to squamous cell carcinoma (SCC), BCC is more common on areas of only moderate exposure, e.g. upper trunk in men and women and lower legs in women. Yet, up to 85 percent of BCCs occur in the sun-exposed head and neck region. Several studies have illustrated the link between UV exposure and BCC to be weaker than the link between UV exposure and AK or squamous cell carcinoma.
