The role of screening in the management of skin cancer.

The incidence of skin cancer has been rising at an alarming rate for the past several years. This poses a significant public health problem in the United States. Detection and treatment of melanoma early in its course is critical for improved outcome. Of the approaches to cancer control that can reduce mortality from melanoma and nonmelanoma skin cancer, screening holds the greatest promise for a rapid and major impact. Prevention and early detection are crucial in reducing morbidity and mortality from skin cancer. For a number of reasons, however, the full effect of screening for both melanoma and nonmelanoma skin cancers has not been achieved. Controversy exists regarding who should perform screening, who should be screened, and whether screening should be performed at all. It is clear that melanoma and nonmelanoma skin cancer control programs combining primary prevention, education, and screening are in developmental stages. This review will discuss the advantages and disadvantages of screening for skin cancer.
