Dear jilltaylor: The concern regarding soy products relates to the phytoestrogens that are contained in soy products. These act like weak
estrogensHormone replacement therapy in the body. There has been some research that shows that phytoestrogens may offer some protection against breast cancer in premenopausal
womenWomen's way. The jury is still out on the effects of soy in post-menopausal
womenWomen's way and in
womenWomen's way with breast cancer. Some oncologists will recommend against using soy products in women with estrogen positive cancers. Because there is no hard evidence proving that these products increase recurrence, some feel comfortable with using these products in moderation. You should discuss your situation with your oncologist.
