Prostate cancer test may have drawbacks

(KABC) Wake Forest University doctors discovered five variations in men's DNA linked to an increased risk of prostate cancer. Men with only one of the genetic variants have a 50 percent greater chance of getting prostate cancer, but men with four or five of the risky genes have a 400 percent increased risk.

Experts say the test won't be able to identify which cases are aggressive or low-risk, and having the genes doesn't mean a man will get prostate cancer. Some men would be mistakenly classified as high-risk.
