A Dutch study evaluated 296 postmenopausal and 87 premenopausal women with breast cancer. Researchers measured plasma isoflavones in these women. They compared levels to 383 matched controls. Soy is rich in isoflavones. They are considered phytoestrogens (weak plant estrogens).
Women in the highest tertile of genistein had nearly a one-third reduced risk of developing breast cancer. While researchers measured other isoflavones and lignans, they found significant protection only from genistein.

I don't think that soy is the menace many do. In fact, it could help many women with breast cancer. However, I do think that most of the soy you consume should be from fermented soy products. These include miso, tempeh, and natto in contrast to non-fermented tofu.
Additionally, about 100% of the soy grown in this country today is GMO. I don't want Monsanto's Roundup Ready genes in my body. Neither should you. If you eat soy, make sure that it's organic.
