Breast cancer is the breast glandular epithelial cells of cancer-causing factors in a variety of roles, the occurrence of a genetic mutation, resulting in uncontrolled cell proliferation. Because the biological behavior of cancer cells has changed, showing a disorderly proliferation of malignant unlimited.
Tokyo, Japan, National Cancer Medical Center researchers have found that high concentrations of genistein in the blood than women with low concentrations of the chances of women suffering from breast small, rich in soy genistein.

The researchers compared 144 women with breast cancer and 288 women without breast cancer blood samples, analysis genistein concentration and breast cancer risk relationship.
The results showed that genistein concentration of women in the highest risk of breast cancer is the concentration of women in the lowest 1 / 3. Another recently published study shows that older women often eat soybeans lower risk of heart disease. However, the researchers warned that excessive intake of genistein and other soy isoflavones, especially those supplements, may also increase the risk of breast cancer risk.
