Hand pattern indicates prostate cancer risk

The ratio of digit lengths is fixed in utero, and may be a proxy indicator for prenatal testosterone levels. The researchers from the UK analysed the right-hand pattern and prostate cancer risk in 1524 prostate cancer cases and 3044 population-based controls.

Compared with index finger shorter than ring finger (low 2D:4D), men with index finger longer than ring finger (high 2D:4D) showed a negative association, suggesting a protective effect with a 33% risk reduction (odds ratio, OR, 0.67). Risk reduction was even greater (87%) in age group less than 60 (OR 0.13).

The researchers concluded: "Pattern of finger lengths may be a simple marker of prostate cancer risk, with length of 2D greater than 4D suggestive of lower risk."

It will be interesting to see how this information is used.
