Green tea "cuts prostate cancer"

Drinking green tea can reduce a man's risk of suffering from advanced prostate cancer, a study suggests.

Around 50,000 Japanese men aged between 40 and 69 were monitored for up to 14 years, and a total of 404 were diagnosed with prostate cancer, including 114 with advanced forms of the disease.

Green tea consumption had no effect on localised cancer, but men who drank five or more cups a day were half as likely to have advanced prostate cancer as those drinking less than one cup.

The new research is published in the American Journal of Epidemiology.

Prostate cancer is the most common men's cancer, and around 35,000 new cases are diagnosed in the UK each year, leading to 10,000 deaths.

Dr Chris Hiley, from The Prostate Cancer Charity, said: "This study looks at the link between drinking green tea and advanced prostate cancer.

"Green tea contains powerful antioxidants, called polyphenols. Drinking green tea may protect against the development and growth of prostate cancer.

"However, we still don't know enough about the link between green tea and prostate cancer. The studies, so far, are contradictory.

"There could be more complicated interactions resulting from the marked differences between Asian and Western diets, and not just Japanese men's green tea drinking habits."
