Probably not a replacement for other types of testing, but it is easy to check and only needs to be done once.

Prostate Cancer Risk Is Lower in Men With Long Index Fingers, Study Finds - Bloomberg
Men with long index fingers are at lower risk of prostate cancer, a study found. Scientists in the U.K. who compared the hands of 1,500 prostate cancer patients and 3,000 healthy men found that those whose index was longer than their ring finger were 33 percent less likely to develop the potentially fatal disease.
“Relative finger length could be used as a simple test for prostate cancer risk,” said Ros Eeles, one of the study’s lead authors and a researcher who investigates links between genetic makeup and tumors at London’s Institute of Cancer Research, in a statement. The study was published in the British Journal of Cancer today.
