If you didn't believe me about the risk of tanning beds before, please stop and read this now. Assessments by World Health Organization oncologists have concluded what we've suspected for years — that the UV light used in artificial tanning beds is indeed a carcinogen, one at the same grade of toxicity as gamma radiation and plutonium. This means that instead of saying that the radiation from a tanning bed might cause cancer, now we know that it undoubtedly will. Exposure to a tanning bed beginning before the age of 30 increases your risk of skin cancer by a whopping 75 percent, and melanoma is one of the most painful, deadly forms of cancer. So, really: don't expose yourself to such a big risk. For more information on this story, read the Review of Human Carcinogens—Part D: Radiation just published on The Lancet's Oncology journal website.
