Researchers from Johns Hopkins University found that natural compounds from soy and other plants reduce the risk of breast cancer recurrence and increase the chances of survival in patients. The results of the research were published at: magazine JNCI Cancer Spectrum.
The authors conducted a meta-analysis of 22 studies examining the effects of soybean, kale, and green tea consumption on breast cancer recurrence and all-cause mortality. Soy isoflavones were found to be associated with a 26% reduction in the risk of breast cancer recurrence when taken at 60 milligrams per day. This is equivalent to two to three glasses of soy milk, 3 ounces of tofu, or half a cup of cooked soybeans per day. The results were most notable among postmenopausal women.
Additionally, drinking green tea reduces the risk of breast cancer recurrence by 44% in women with stage I or II breast cancer. The greatest effect was observed when drinking three to five glasses a day. Cruciferous vegetables had the smallest effect.
“It is important to emphasize that these studies were conducted on women undergoing medical or surgical treatment, so these foods and phytonutrients should not be considered as alternatives to treatment,” the authors said.
Previous scientists studied The hereditary nature of diffuse gastric cancer.
