The content of antioxidants in green tea has long been known to prevent the development of cancer cells. However, a recent study in Japan showed no relationship at all between green tea consumption with risk of breast cancer.
Several previous studies mentioned that the consumption of green tea may help protect women from breast Cancer. That’s because the content of polyphenolic compounds contained in green tea can indeed protect against breast Cancer.
Polyphenols fall into a very potent antioxidant. This compound will neutralize free radicals that cause cancer. However, recent large-scale study in Japan showed different findings. Drinking green tea did not have a relationship with Breast healthy .The result findings are published online in the October 28 issue of the journal Breast Cancer Research.
“We found no overall relationship between Green tea intake and breast Cancer risk among Japanese women who used to drink green tea,” said study leader, Dr. Motoki Iwasaki, from the epidemiology and prevention at the Research Center for Cancer Prevention and Screening of the National Cancer Center in Tokyo, Japan.
“Our findings suggest that consumption of Green tea is drunk regularly is not possible to reduce the risk of someone suffering from breast Cancer,” he said as quoted by page Healthday.com.
For this study, Iwasaki team members collected data from 53,793 women who were surveyed between 1995 and 1998. They ask the question how many of the participants were consuming Green tea.This question was given at the beginning of the study and proposed again five years later. During the second survey, the researchers also asked about the two types of green tea Sencha and Bancha / Genmaicha.
Researchers noted, among women, about 12% of them consumed less than one cup of green tea in the other 27% in a week .While drinking five or more cups a day.This study also included female respondents who drank more than 10 cups a day. For nearly 14 years monitored, 350 women from the study participants had breast Cancer.
However, the researchers found no association between green tea drinking and risk of breast cancer. In the study, Iwasaki says that one of the strengths of this study is already wants to achieve those objectives set so that the number of participant information can be collected before the diagnosis of breast Cancer.
“So avoid that is usually inherent in research that uses case study method,” he said.
Dr. Stephanie Bernik, breast cancer surgeon at Lenox Hill Hospital in New York City, United States, said it was difficult to say that there is no benefit at all from consuming green tea.
“Maybe there is no benefit, specifically for breast Cancer,” he said. Bernik noted that many women who have breast cancer are interested in alternative treatments if medical action of the West can not cure.”We are always looking for more knowledge about how to treat breast cancer and reduce the incidence of breast cancer,” he said.”Women are definitely interested in what way they can have a healthy lifestyle,” continued Bernik.
Jennifer J Hu, a professor of epidemiology and community Health at the University of Miami School of Medicine’s Sylvester Comprehensive Cancer Center, United States, adding that the problem with population-based study is that when you try to see one single factor, you will not take into account risk factors another conclusion that can affect research.
“Also, just by drinking green tea, you do not get enough of the way (possibly compound to fight cancer) to make much difference,” he said.Based on these problems, Hu did not think that this research is to answer the question whether or not green tea can help a person prevent breast cancer.
Breast cancer is said to be worth a frightening disease for a woman. Worldwide, breast Cancer is the second largest cause of death after lung cancer, followed by colon Cancer.
