Experts Provide Caveat To Sunscreen-Melanoma Study Findings.

Medscape (5/4, Mulcahy) reported, "In the past year, sunscreen was shown -- for the first time -- to prevent melanoma in one of the only randomized controlled trials ever conducted on this subject." However, "there is a caveat about the results that has important public health implications and was not highlighted in the original study, according to a letter published online April 4 in the Journal of Clinical Oncology." People who participated in the trial were middle-aged Australians whose sun exposure occurred during the course of their daily activities. In other words, their sun exposure was incidental, not intentional, as would be the sun exposure of dedicated beachgoers. Therefore, the authors of the letter say that "white people in other parts of the world should not interpret the study results as a 'green light' to tan on the beach."
