A new research claims that men whose index finger is longer than their ring finger are at lower risk to develop prostate cancer, The Wall Street Journal reported Tuesday.

The British Journal of Cancer said that researchers studied the ratio between the 2nd and 4th finger of the right hand in 1,524 prostate-cancer patients and 3,044 fit people over 15 years. Men with longer index fingers were 33 percent less likely to develop prostate cancer, and men under 60 had an 87 percent lower risk.

In the prostate-cancer group, index fingers were longer in about 23 percent of the participants and shorter in 57 percent.
In the control group, index fingers were longer in 31 percent and shorter in 52 percent. The rest of the men had fingers of equal length. The findings are in line with a new study of 366 Korean men, which found a significant association between digit ratio and prostate-cancer risk.
