It may be packed with anti-oxidants but green tea does not protect against breast cancer, according to an extensive study. Previous research on both animals and human cells had suggested the hot drink could boost the body's defenses against the cancer.
However, the latest analysis looking at 54,000 women found no association between drinking green tea and breast cancer risk. A five year study found no link between drinking green tea and reducing a person's risk of breast cancer
Dr Motoki Iwasaki, from the National Cancer Center, Tokyo, worked with a team of researchers to carry out the study. He said: 'Results from human studies have been inconclusive. Our large-scale, population-based prospective cohort study is one of the first to include a wide range of tea intakes; women who drank green tea less than 1 cup per week to those who drank 10 or more cups per day. It found no overall association between green tea intake and the risk of breast cancer"
来自东京的癌症专家Motoki Iwasaki表示，这个“以广泛人类为对象”的实验规模是巨大的，实验对象从每周喝1杯茶到每天喝10杯茶都进入到了我们调查的方位。由于调查者的每日 “摄入的绿茶量”不一样， 实验的结果还不能100%的说明问题，但是饮用绿茶和抵抗乳腺癌不存在关系是铁定的事实了。
Speaking about the survey, Dr Iwasaki said, 'The other major strength of the present study was its prospective design, in which information was collected before the subsequent diagnosis of breast cancer, thereby avoiding the exposure recall bias inherent to case-control studies. 'Drinking green tea as a beverage is unlikely to reduce the risk of breast cancer regardless of green tea type and number of cups'.
