Long Ring Finger = Less Prostate Cancer?

According to the British Journal of Cancer, a new study by London’s Institute of Cancer Research finds that finger length might be an indicator of prostate cancer risk. Digit length is determined by the amount of sex hormones— especially testosterone—that a baby is exposed to in utero. After observing the right hand patterns of 1524 men with prostate cancer and 3044 population based controls, the study found that men whose index fingers were longer than their ring fingers had a 33% reduction in their risk of prostate cancer.
