Caffeine and Skin Cancer

More than a million new cases of skin cancer are diagnosed every year, making it the most common form of cancer in the United States. A new study shows that caffeine might reverse, damage to skin caused by the sun.
"There's epidemiological data along those lines and the interesting more recent thing is that caffeine appears to be able to do that when you apply it topically," said dermatologist Dr. Paul Ngheim.
Scientists found that caffeine, when applied directly to damaged skin, blocked pre-cancerous cells from dividing and becoming skin cancer.
"Caffeine, at least in mice and in cells, can reverse that damage in part by actually getting rid of the cells that are most damaged, so that more healthy cells can grow in," said Dr. Ngheim.r
Researchers don't believe caffeine would ever be an effective treatment for those already with skin cancer.
The benefits are to prevent damaged skin from becoming cancerous.
