The length of a man's fingers can provide clues to his risk of prostate cancer, according to new research. A British Journal of Cancer study found men whose index finger was longer than their ring finger were significantly less likely to develop the disease.
Researchers made the discovery after comparing the hands of 1,500 prostate cancer patients with 3,000 healthy men. The length of the fingers is fixed before birth and is thought to relate to sex hormone levels in the womb.
Being exposed to less testosterone before birth results in a longer index finger and may protect against prostate cancer later in life, say researchers at the University of Warwick and the Institute of Cancer Research.
One of the report authors, Professor Ros Eeles, said more studies would be needed, but if these confirmed the findings it could be used a simple test for prostate cancer risk.
