Those who work their butts off physically often enjoy a bit of added protection against cancer. And sometimes they don't. Just ask Olympic swimmer Eric Shanteau, who was just recently diagnosed with testicular cancer.

Shanteau, 24, won't let cancer stop him from going for Gold in the 200-meter breaststroke -- he plans to delay his surgery until after he competes. Don't worry. The swimmer will be closely monitored and will drop out of the Olympics should his cancer appear to spread. "By no means am I being stupid about this," says Shanteau, who has high hopes for a successful recovery.

According to the American Cancer Society, testicular cancer, one of the most curable forms of cancer in the United States, will strike about 8,090 U.S. men in 2008. Because treatment is so successful, the risk of dying from this cancer is very low: about 1 in 5,000.
