Ray has written about the powerful estrogenic effects of soy, so this study does not surprise me but it is the first one I see that draws a conclusion that soy may be contra-indicated for breast cancer. So far all other soy studies claimed that it either prevented cancer or helped survival. A step in the right direction IMO.
