Research evidence does not support a link between green tea consumption and reduced risk of breast cancer, reports Dr Motoki Iwasaki in a study of 53,793 Japanese women. The survey, conducted from 1995 tol998, included questions regarding green tea consumption. The second part of the survey even asked the women to identify the type of gree'n tea consumed: Sencha or Bancha/Genmaicha.Iwasaki, from the Epidemiology and Prevention Division at the Research Center for Cancer Prevention and Screening of the National Cancer Center in Tokyo, explains that "Our findings suggest that green tea intake within a usual drinking habit is unlikely to reduce the risk of breast cancer. Twenty-seven percent of the women surveyed reported drinking 5 or more cups of green tea per day, whereas 12% drank less than 1 cup of green tea per week. However, some participants reported drinking 10 or more cups per day. These same women for monitored for over 14 years, and 350 of them developed breast cancer. Thus, the researchers concluded no association between drinking green tea and a reduction in the risk of developing breast cancer.
