There Is No Such Thing As A Safe Tan: GW Researchers Break Tanning Misconceptions
From the 24 July 2012 article at Medical News Today
A new study conducted by GW School of Medicine and Health Sciences (SMHS) researchers Edward C. De Fabo, Ph.D., Frances P. Noonan, Ph.D., and Anastas Popratiloff, M.D., Ph.D., has been published in the journal Nature Communications. Their paper, entitled “Melanoma induction by ultraviolet A but not ultraviolet B radiation requires melanin pigment,” was published in June 2012.
“This is the first time that UV-induced melanin formation (tanning), traditionally thought to protect against skin cancer, is shown to be directly involved in melanomaformation in mammals,” said De Fabo, who is professor emeritus at SMHS. “Skin melanoma is the most lethal of the skin cancers. Our study shows that we were able to discover this new role for melanin by cleanly separating UVA from UVB and exposing our experimental melanoma animal model with these separated wavebands using our unique UV light system designed and set up at GW. Dermatologists have been warning for years there is no such thing as a safe tan and this new data appears to confirm this.” ..

“Also new is our discovery that UV induction of melanin, as a melanoma-causing agent, works when skin is exposed only to UVA and not UVB radiation. This is especially important since melanoma formation has been correlated with sunbed use as many epidemiological studies have shown. One possible reason for this is that tanning lamps are capable of emitting UVA radiation up to 12 times, or higher, the UVA intensity of sunlight at high noon. Melanin plus UVA is known to cause photo-oxidation, a suspected, but still to be proved, mechanism for the formation of melanoma as we describe in our study,” De Fabo said.

If you’re like most people, chances are you’ll take any opportunity to throw on a pair of shorts and soak up a little vitamin D. Summer is the season for taking advantage of every opportunity you can to be outdoors, and while you’re enjoying the weather, you’re also probably happy to work on achieving a nice golden tan while you’re at it. But through all of the barbecuing, swimming, hiking, and good old fashioned sunbathing, it might just slip your mind to lather on a little SPF 40. When it comes to enjoying the great outdoors, it’s in your best interest to make sure that you do so with the proper protection. Skin cancer rates have skyrocketed in recent years, and while popular culture dictates that a beautifully bronzed body is the ultimate summertime achievement, the obsession with having a great tan is also having some scary health effects. While other cancer rates decline, fatalities from skin cancer continue to rise, and most people don’t realize just how much their risk increases with too much sunshine. While a little dose of golden rays is good for you, most people take that to an extreme, and the impacts of long-term tanning can be more deadly than they realize. The following infographic looks into the causes and effects of the rising skin cancer rates, and it might make you think twice before skipping out on the sunscreen.
