Tanning beds as deadly as arsenic in causing cancer
International cancer experts have moved tanning beds and other sources of ultraviolet radiation into the top cancer risk category, deeming them as deadly as arsenic and mustard gas. 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% when people start using tanning beds before age 30. Experts also found that all types of ultraviolet radiation caused worrying mutations in mice, proof the radiation is carcinogenic. Previously, only one type of ultraviolet radiation was thought to be lethal. The new classification means tanning beds and other sources of ultraviolet radiation are definite causes of cancer, alongside tobacco, the hepatitis B virus and chimney sweeping, among others.
