Green Tea and Prostate Cancer:

A study by researchers at Japan’s National Cancer Centre carried out with 50,000 men aged 40-69 over the period of up to 14 years from 1990 was published in the American Journal of Epidemiology. The study shows drinking green tea may reduce the risk of advanced prostate cancer. Men who drank five or more cups a day might halve the risk of developing advanced prostate cancer compared with those who drank less than one cup a day.

Norie Kurahashi, a scientist who took part in the study commented although there is no guaranteed green tea can reduced risk of advanced prostate cancer, the results do point to the hope that green tea reduces the risk of advanced prostate cancer.

Prostate Cancer is much less common among Asian men than Western men, and maybe partly due to the effects of the high consumption of green tea in Asia, the study suggest. Further study is required British charity Cancer Research UK says on its website that a study of almost 20,000 Japanese men published in the British Journal of Cancer in 2006 found no relationship between green tea and prostate cancer.

Green Tea for Cancer Prevention:

At the Sixth International Conference on Frontiers in Cancer Prevention, sponsored by the American Association for Cancer Research, a project led by Dr. Hang Xiao from the Ernest Mario School of Pharmacy at Rutgers University, Piscataway, New Jersey, shown that an extract of green tea wards off colorectal cancer. The particular substance in question is the standardized green tea polyphenol preparation (Polyphenon E) which limits the growth of colorectal tumours in rats treated with a substance that causes the cancer.

The results of this project are consistent with previously published results, which showed that green tea consumption was associated with lower colon cancer rates in Shanghai, China. Dr Xiao noted the tea polyphenols decreased the number of malignant tumors per rat by 80 percent compared to the control group. When the researchers analyzed blood and colon tissue samples they found a “considerable amount of tea polyphenols in those samples in treated animals and those levels of tea polyphenols were comparable to the human situation following the ingestion of tea leaves or tea beverage,” Xiao noted.
