Green tea may halve prostate cancer risk: Study

TOKYO: Drinking five or more than cups of greenish tea a twenty-four hours could halve the hazards of developing advanced prostate gland gland cancer, according to a Nipponese study.A research squad from Japan's Health Ministry surveyed 49,920 work force aged 40-69 across the state in 1990 and 1993 and followed up on their wellness until 2004, the National Cancer Centre said.During this time, 404 work force were newly diagnosed with prostate cancer, of whom 114 had advanced cases, 271 were localised, and 19 were of an undetermined stage. An analysis establish the hazards of having advanced prostate gland gland malignant neoplastic disease was 50 percentage less for work force who imbibe five or more than cups of greenish tea a twenty-four hours compared with those who have got less than one cup, the survey said."Green tea was not associated with localised prostate cancer," the research grouping said in a report. But it added: "Green tea may be associated with a decreased hazard of advanced prostate gland gland gland cancer."The research squad said a matter called catechin in greenish tea may be contributing to reducing hazards by curbing degrees of testosterone, a male internal secretion seen as a hazard factor to prostate cancer.The relative incidence of prostate malignant neoplastic disease is much less in Asiatic than Horse Opera populations. The survey began on the premise that this may be linked to the high ingestion of greenish tea in Asiatic populations. The determinations were published in the online version of the American Diary of Epidemiology.
