No such thing as a safe tan
ScienceDaily (July 23, 2012) — 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.
"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 melanoma formation 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."
