Can a woman who has had breast cancer eat soy?

Unkown. So far the data for eating soy is okay and may be beneficial. I usually recommend staying away for soy supplements (ex. Daily soy protein shakes, estroven) because of the estrogenic properties.
Controversial. This is a controversial topic. Some feel that by the time you have breast cancer the horse is already out of the barn and your diet will have little effect on outcomes.
