Breast Cancer :: Green tea may reduce breast cancer risk

Drinking five cups of green tea a day can reduce the risk of breast cancer by 22 per cent, claims a meta-analysis of previous studies, the same studies that the FDA recently said contained very little science to support the claims.

Epidemiological and laboratory studies have linked green tea to reduced risks of breast, lung, prostate and ovarian cancer. As a result, green tea sales have been steadily increasing in Europe and the US.

The anti-cancer effects of tea have been linked to the polyphenol content of the tea. Green tea contains between 30 and 40 per cent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 per cent.
