May reduce the risk of breast cancer

A decreased risk of developing several malignancies has also been associated with soy-rich diets. One recent assessment of 12 research, for instance, found that women who consumed more soy before getting a cancer diagnosis may have a 16 percent reduced probability of dying from the disease than those who consumed the least. High soy consumption before and after diagnosis may also cut postmenopausal women's chance of developing breast cancer again by up to 28%. The results of this study, however, imply that premenopausal women could not reap the same advantages. On the other hand, another research claims that pre-postmenopausal women who consume diets high in soy may benefit from a 27 percent reduced risk of cancer.

But only Asian women were shown to benefit from soy's defensive properties, whereas Western women seemed to gain little. These studies suggest that certain women who consume diets high in soy may experience a reduced risk of breast cancer. However, further research is required to pinpoint which females would profit the most.
