Wow, I am vegetarian too and eat tofu regularly, but I am now taking Tamoxifen and have estrogen-receptor-positive BC. I had NO IDEA about this recommendation of moderating the soy intake. My onc is never really keen on discussing diet while on treatment, so I wonder who I could ask. The last time I asked her whether something was good for me she said to eat as I pleased, as the food trends to avoid BC recurrence come and go "with the interest of the US economy. If milk has to be sold, you'll see in the news milk is good for you. The following year they'll have overstock of something different and that will be the next big thing against cancer". I can see her point, but this left me a bit worried!
