Are we overemphasizing sun avoidance in protection from melanoma?

Abstract

The public health effect of melanoma in the United States is undeniable as approximately 60,000 diagnoses of invasive melanoma and 8,000 deaths from melanoma are expected in 2007. Due to the poor outcomes associated with treating advanced cases of melanoma, substantial public health resources have been devoted to prevention efforts. Of the various factors involved in the pathogenesis of melanoma, including genetic predisposition, immunosuppression, and UV radiation, decreasing UV exposure has attracted the most attention for decreasing the public health effect of melanoma. Although sun avoidance may be an important measure for reducing the public health effect of melanocytic and keratinocytic malignancies, educational and media campaigns to encourage sun avoidance have failed to achieve the desired behavior changes in young people, have had limited effect on elderly patients who have already experienced decades of damaging sun exposure, and most importantly have failed to decrease the incidence of melanoma. We believe the best method to reduce deaths from melanoma is to emphasize early detection and treatment of suspicious lesions through combined efforts of both patients and providers.
