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. 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 research was published online in the medical journal Lancet Oncology recently, by experts at the International Agency for Research on Cancer in Lyon, the cancer arm of the World Health Organization.
“People need to be reminded of the risks of sunbeds,” said Vincent Cogliano, one of the cancer researchers. “We hope the prevailing culture will change so teens don’t think they need to use sunbeds to get a tan.”
Most lights used in tanning beds give off mainly ultraviolet radiation, which cause skin and eye cancer, according to the International Agency for Cancer Research. Cogliano cautioned that ultravoilet radiation is not healthy, whether it comes from a tanning bed or from the sun.

How does the sunlight damage the skin?

Simply put, ultraviolet radiation (UVA and UVB particularly), be it from the sun or tanning beds, damages the DNA of skin cells. To make matters worse, the thinning of the Earth’s ozone layer is believed to increase UV radiation levels. It takes many years before enough microscopic damage accumulates to create wrinkles and other visible signs of skin change.
Government health officials estimate that as much as 75 percent of UV damage occurs before the age of 18. About 80% of the UVB rays hit the epidermis causing reddening. Ninety -five percent of the rays hitting the Earth are UVA rays and they easily penetrate the dermis causing premature aging and wrinkles.
Sun block that absorbs both UVA and UVB rays should be applied every two hours. Layered clothing, glass and dense clouds can minimize UVB rays. UVA can penetrate cloud cover, light clothing and un-tinted glass. Both UVA and UVB rays have been linked to the production of cancer.
