Thank you so much for your answer,I had a feeling that those products can cause breast cancer and you have confirmed it.I pray and hope that all goes well for you too.
Soy and estrogen: I've read much conflicting information about this, but what I believe we can say for sure is that soy products (soy milk, tofu, edamame) supply a weak form of estrogen from plant sources, called phytoestrogens. With menopause your body stops making estrogen. Eating soy products seems to boost the estrogen a bit, but is that good? I was a regular consumer of soy milk, tofu, edamame and flax seed after menopause. After my diagnosis of breast cancer (estrogen positive) my oncologist recommended I avoid soy products because even the weak phytoestrogens may stimulate cancer cells. Research is not conclusive but better to be safe. As the addage goes, 'all things in moderation.'
