DNA variations linked to increase prostate cancer risk

January 16, 2008 2:31:27 PM PST
Doctors from Wake Forest University have discovered five tiny variations in men's DNA that are linked to an increased risk of prostate cancer.

They found men with only one of the genetic variants have a 50 percent increase in prostate cancer risk. But men who have four or five of the risky genes have more than a 400 percent chance of prostate cancer than men without the variants.

Researchers are so struck by the findings that a university lab plans to offer blood test for these genes in the near future.

Experts say while these findings may lead to a useful gene test soon, it's not ready yet.
