International cancer experts have moved tanning beds and ultraviolet radiation into the top cancer risk category, deeming both to be definite causes of cancer.
For years, scientists have described tanning beds and ultraviolet radiation as "probable carcinogens."
A new analysis of about 20 studies concludes the risk of skin cancer jumps by 75 percent when people start using tanning beds before age 30.
Cogliano said the classification means experts are confident that tanning beds cause cancer, but he noted they may not be as potent as other carcinogens like tobacco or arsenic.
According to the studies reviewed by Cogliano and colleagues, using tanning beds caused about a 20 percent increased relative risk of developing melanoma, the deadliest kind of skin cancer.
Cogliano said it was impossible to know how many benign skin cancers might be caused by tanning beds, because of complicating factors like exposure to regular sunlight. He and colleagues examined data from more than 7,000 melanoma cases and found a strong association between tanning bed use and the disease. He compared the link to that found between tobacco and lung cancer.

There is no way to know if the above recommendations are correct. The ONLY way to know is to test your blood. You might need 4-5 times the amount recommended above. Ideally your blood level of 25 OH D should be 60ng/ml.
