Green Tea May Halve Prostate Cancer Risk: Japanese Study

Posted by

More great news about drinking green tea!  According to a recent Japanese study published in the online version of the American Journal of Epidemiology, drinking five or more cups of green tea a day could halve the risks of developing advanced prostate cancer.

A research team from Japan's health ministry surveyed 49,920 men aged 40-69 across the nation in 1990 and 1993 and followed up on their health until 2004, the National Cancer Centre said.  During this time, 404 men were newly diagnosed with prostate cancer, of whom 114 had advanced cases, 271 were localised, and 19 were of an undetermined stage.

An analysis found the risks of having advanced prostate cancer was 50 percent lower for men who drink five or more cups of green tea a day compared with those who have less than one cup, the study said.

The incidence of prostate cancer is much lower in Asian than Western populations. The study began on the assumption that this may be linked to the high consumption of green tea in Asian populations.
