New Study on Fathers and Daughters and Prostate Cancer

Fathers who only have daughters could be at an increased risk for prostate cancer.

According to researchers at Columbia University, it may have something to do with a Y chromosome defect.

A child's sex depends on whether he or she receives an X or a Y chromosome from the father.

After studying more than 38,000 fathers, researchers say men who had no sons at all had a 40 percent increased risk of prostate cancer and the more daughters they had, the greater the risk.

However, experts say more research needs to be done.
