So, for example, at noon when the sun is highest, you have little to no shadow, and that is the best time to try to stay indoors or in the shade."
Skin cancer -- including melanoma and nonmelanoma malignancies -- is the most common of all cancers, accounting for about half of all cancers. An estimated one million cases of nonmelanoma skin cancers are diagnosed annually in the United States. Most are basal cell -- about 800,000 to 900,000. Squamous cell cancer occurs less often -- perhaps 200,000 to 300,000 cases annually. People do not often die of these cancers. About 1,000 to 2,000 people die of nonmelanoma skin cancer each year in the United States, according to the American Cancer Society.
Melanoma, on the other hand, causes most skin cancer deaths, even though it accounts for just 3 percent of all skin cancer cases. The American Cancer Society estimates there will be 59,940 new cases of melanoma in the United States this year, and about 8,110 people will die of the disease.
