Fermented soy

Any thoughts on fermented soy? I have ER- breast cancer, chemo induced menopause. I also was on a soy formula as an infant as I could not tolerate anything else. And have psoriasis. I have read that fermented soy is an anti-inflammatory and works well with turmeric which is an anticarcinogenic and also anti-inlfammatory recommended for Psoriasis too. I had decided it was worth a try and when trying to look up info on how to do it myself was just bombarded with the adverse effects of soy. Thank you so very much for any input. Donna
