Solar Radiation And Skin Cancer

Skin cancer (basal and squamous cell carcinomas) is approximately 600,000 cases per year in the United Stats, almost all of which are thought to be induced by exposure to sunlight. For comparison, the incidence of lung cancer in the United States is approximately 160,000 cases per year, so solar radiation causes even more cancers than smoking. Fortunately, however the nonmelanoma skin cancers metastasizes very slowly and are consequently highly curable. This is reflected in the fact that these skin cancers result in only about 2,500 deaths per year in the United States. In contrast, lung cancer is highly lethal, resulting in over 140,000 deaths annually in the United State. Therefore, although nonmelanoma skin cancers caused by solar radiation are extremely frequent, they account for a comparatively small fraction of cancer mortality.
