In an American study of 265,000 people over 12 years showed that those who ate a kind of bean mold daily risk of stomach cancer than those who do not use low soy exactly the techniques
Two other studies in China found that women use less soy foods (less than 1 time / week) with the rate of lung cancer and breast cancer 2 to 3.5 times higher than women taking daily.
In a study where subjects are Chinese-American, Japanese, and Filipino, the researchers noted an inverse relationship between the level of consumption dimensional molds beans and breast cancer risk: Parking on site for more women at risk for breast cancer than women who do not use low or use less beans mold. A similar finding was also noted in a study in Singapore and Hawaii.
Endogenous hormones and exogenous hormones (exogenous hormones) are related to a variety of cancers. In men, those of male hormones (androgens) often have higher risk of prostate cancer than those with low levels of male hormones. In women, the risk of breast and ovary cancer generally increases with the level of phytoestrogens (or estrogen) exactly the techniques
Like other ethnic groups have low hormone levels as well as those with low risk of cancer. Therefore, a hypothesis arises if there is a chemical or food reduces male and female hormones, it can also reduce the risk of cancer.
