In their own trade journal the American Association of Dermatology admits tanning's connection to skin cancer is unclear.

"There is no compelling evidence that suntan parlors have induced a single melanoma."
— Dermatology pioneer Dr. Bernard Ackerman

"We don't have direct experimental evidence."
— AAD spokesman Dr. James Spencer

And yet dermatologists treat cosmetic skin conditions with their own UV tanning equipment. They charge up to $100 a session for what tanning salons provide for $5. So is cosmetic dermatology concerned about public safety, or do they just want their multi-billion dollar business back?
