How can sunless tanners cause cancer? What is DHA?

So, I started experimenting with sunless tanners and bronzers and fell in love with the idea of having a gorgeous glow from a lotion or spray. I found a few that I liked but until this day I am on a quest to find the best. The best smelling, no orange, and most affordable. Just when I narrowed down my search to my favorite few, I see on the morning news..."Coming up next, sunless tanners can cause cancer."
What???  You are kidding me right?

Why do sunless tanners cause cancer? What is the chemical that causes cancer in sunless tanners? How do you get cancer from sunless tanners? Are sunless tanners safe to use? What are the cancer risks with sunless tanners?

What is DHA?

Dihydroxyacetone (DHA) is the chemical found in sunless tanners that make them effective. DHA is what causes your skin to turn brown. DHA does not absorb into the skin so it is not known to be toxic, however, the new studies conducted revealed that DHA can get into your bloodstream through your lips, eyes, and lungs. Which now makes spray tanning a cancer risk.

Should I be worried about exposure to DHA? How does DHA cause skin cancer?

DHA has been listed with the Food and Drug Administration (FDA) since 1973, and has been used in cosmetic preparations for almost 30 years. I guess that fact that DHA is ingredient in many of our cosmetics and we don't eat our cosmetics there was no reason for the FDA to be concerned. Until now. The spray tanning booths release this toxin in the air and is being inhaled directly into our lungs and  then enters our bloodstream witch can cause cancer cells to grow. Very scary! I have used a couple different sunless tanning aerosol sprays in the shower and I always held my breath, ran to the window for air. Kind of a pain but I was always concerned about the spray getting into my lungs so no big surprise with that one, however, who would ever have known that this chemical can enter our bloodstream through our lips and eyes!

What is the Skin Cancer Foundations position on DHA?

New York, NY (June 11, 2012) –There is no clear evidence that DHA (dihydroxyacetone) is harmful to humans if applied topically and used as directed. Although it temporarily adheres to the skin, DHA eventually dislodges as the skin cells shed. The Skin Cancer Foundation bases all of its conclusions on medical studies with human subjects and there are no human medical studies that give us reason to believe that DHA penetrates the skin. 
Furthermore, The Skin Cancer Foundation considers tanning to be out of style and obsolete as a lifestyle. In fact, the Foundation’s Go With Your Own Glow campaign was developed to encourage women to embrace – and protect-- their natural skin tone, whatever its hue. However, for people who feel the need for bronzed skin, the Foundation maintains that spray tanning and self tanners are still safer than UV radiation exposure obtained outdoors or in a tanning bed.
