Using indoor tanning beds can increase the risk of melanoma by 75%—and the US Food and Drug Administration wants you to know it. Ultraviolet (UV) radiation is the biggest environmental risk factor for melanoma and, the more someone uses a tanning bed, the more likely that they will get this aggressive, but preventable skin cancer. A new FDA proposal would downgrade UV sunlamps from 'low' to 'moderate' risk devices and would require labels that warn frequent users to get regular skin checks. The public can comment on this proposal until August 7, 2013.
