Gyn doctors , what is phytosoy and what role does it play in women in 30's with uterine fibroids tumors?can taking pills with soy make tumor bigger?

Phytoestrogens : I think what you are referring to is phytoestrogens which are found in soy products. It appears to have some effect on tissue modulated by normal estrogen like uterus etc. I am not certain if there is any evidence that implicates phytoestrogen in uterine fibroid formation. However, excessive consumption of soy products can cause heavier menustration in some women.
