According to a paper published in the Lancet Oncology, tanning beds may "pose as big a risk as tobacco and asbestos."  The associated press pointed out that "a new analysis of about 20 studies concludes that the risk of skin cancer jumps by 75% when people start using tanning beds before age 30."  According to the associated press, new classifications of ultraviolet radiation mean that  "tanning beds and other sources of ultraviolet radiation are now considered definite sources of cancer."
