At Nagoya University Medical School, Japan, researchers initiated breast cancer in rats. The animals were divided into groups that received no treatment or treatments of various antioxidants including green tea extract. When the experiment ended, there was 93.8% survival in the green tea extract group compared to only 33.3% survival in the control group that received no treatment. The survival rate for the other antioxidants was between 70-80%. It’s important to understand that the breast cancer was so severe that every single animal developed breast cancer. But the green tea extract group had delayed onset, smaller tumors, and triple the breast cancer survival rate. In addition, there were no toxic side effects from the green tea extract. (Hirose, 1994) While this particular breast cancer green tea research study is preliminary, almost 100 studies on green tea and breast cancer have shown remarkable protection through a variety of biological mechanisms including killing cancer cells through apoptosis, protection of normal cells, prevention of cancer adhesion, prevention of cancer initiation, prevention of cancer progression, prevention of cancer metastasis, prevention of angiogenesis, prevention of inflammation, prevention of DNA damage from free radicals, as well as increasing the survival rate. Green tea research One of the most promising areas of breast cancer research is with green tea health benefits. There are also new studies on green tea reducing breast cancer recurrence. Green tea is safe, inexpensive, and available throughout the world. While green tea has not been effective with an occasional genetic breast cancer cell type, or with terminal Stage IV breast cancer, the most cautious estimates of daily green tea on human breast cancer show an average of 22% overall decrease in breast cancer, based on 5 cups daily for at least a year (Sun CL, 2006). The importance of early detection Early detection is the most important factor in the survival rate for breast cancer patients. The 5-year breast cancer survival rate for Stage 1 (Stage I) breast cancer is 98-100% after successful treatment. For Stage 2 (Stage IIa, IIb) breast cancer it drops to 88-92%. Stage 3 (Stage IIIa, IIIb) breast cancer patients face a 5-year survival rate of 49-67% after successful treatment. And Stage 4 (Stage IV) breast cancer patients average 16-20% survival (American Cancer Society). Pay attention to all breast cancer risk factors Since all causes of breast cancer have not been identified or understood, your life may depend on regular exams from your licensed health care provider. We must also pay attention to reducing all risk factors in our lives if we want to improve our breast cancer survival rate. Other risk factors for breast cancer that you can change include adding recommended examinations for early detection, adding daily exercise, quitting smoking, and restricting alcohol to less than one drink daily. Overweight is usually associated with increased breast cancer. Check out weight loss programs including the online Biggest Loser Diet Club. And of course, daily green tea can be an excellent and safe addition to a healthy diet for almost everyone.
