Well, not exactly, but we could be reducing our risk.

Caffeine and exercise may help prevent skin cancer

Having your morning coffee and hitting the gym may be a prescription for staving off skin cancer, U.S. researchers have found.

A study on mice found that the equivalent of drinking two cups of coffee and then exercising dramatically reduced the number of sun-damaged cells that can lead to cancer. In the experiments, one group of hairless mice drank caffeinated water, another exercised on a running wheel and a third group drank and ran on the wheel. All three groups were exposed to cell damaging UVB radiation, the equivalent of spending 15-30 minutes outdoors at midday.

Moderate exercise, such as jogging, coupled with a couple of cups of coffee could ward off skin cancer.
CBC Cell death or apoptosis, the body's way of killing off DNA-damaged cells, was observed in all three groups. But the group of mice that drank caffeine and exercised had a 400 per cent increase in cell death, versus 120 per cent for the exercisers and 95 per cent increase for the caffeine drinkers.

The studies, conducted in the Susan Lehman Cullman Laboratory for Cancer Research at Rutgers' Ernest Mario School of Pharmacy, will appear in the July 31 Proceedings of the National Academy of Sciences.

They follow previous studies that showed both caffeine and exercise in isolation inhibited ultraviolet light-induced skin cancer. Caffeine has been linked to a reduction in liver cancer and breast cancer, and exercise has been shown to reduce the risk of colon cancer, among others.

"Because of those studies, we looked at the combination and found that we were getting a very dramatic effect in ultraviolet light-induced apoptosis," Allan Conney, director of Rutgers' Cullman Laboratory and one of the paper’s authors, told CBC News.

Conney said that scientists don't know why the combined effect of caffeine and exercise is much greater in preventing skin cancer than just drinking caffeinated beverages or exercising. He says there are some theories that both can decrease tissue fat, but more research is needed in identifying the mechanisms that come into play.

"I think it's important to do the human studies," Conney said. One of the areas scientists will be exploring is how much exercise will humans have to do to get the protective effect, he said, noting that the mice in the study groups ran about 3.2 km per day. "That needs to be quantified in people — those who do moderate exercise, light exercise — to see if there's a difference in risk in different populations."

The occurrence of skin cancer has been increasing in Canada at a fairly constant rate over the past 30 years, according to Health Canada. In 2005, there were roughly 78,000 new cases of basal and squamous cell carcinomas reported and about 4,400 new cases of malignant melanomas.

yes, but sun exposure. Out on the bike some days, maybe five hours. I use good sunscreans. Still my arms get all itchy from the sun and ocassionally peel.

Woohooo!! For once, I'm on the right side it. Just by pure dumb luck of course. Me and my little jazzed up mouse buddies are gonna live forever.

You could simplify that, since Java has its own garbage collection.

Haha...

sweet!

Well, OK. I'll keep drinking a cup of coffee in the morning and riding my bike to work, but nothing beats:

1. sun protection.

2. regular exams.

If you have a mole or skin patch that changes, see the doctor!

I had a rather large malignant melanoma removed from my side that I had looked at soon after it began to darken. Had I ignored it, I may not be writing this four years later.

Now that I have a history of skin cancer, any time any skin patch shows up, it gets carved out. It sounds brutal, but it's a small price to pay, considering the alternative. My latest skin patch removal still has the stiches in.

For the record, I am 50, and a redhead. Well, except for the top of my head, anyway.

The up side is, that I will not have saggy, baggy skin as I age!

So, since we're kind of on the subject, how does everyone here feel about the fact that sunscreen contains carcinogens? Doesn't that seem a little counter productive? What about the fact that vitamin d (produced during exposure to the sun) helps to prevent cancer?
