soy and phytoestrogens help hormonal negatives....

[RobinP]

I was shocked to read that soy may actually help inhibit cancer cell growth in hormonal negatives. Read on in the following excerpt and article:

"Perhaps the most clinically promising data concern the ability of phyto-oestrogen compounds to inhibit the proliferation of ER-negative breast cancer cultures and tumour xenografts in rodents. Although ER-positive cells are often growth stimulated by low phyto-oestrogen concentrations, stimulatory effects have not been reported in cells devoid of functional ER. Phytoestrogen compounds may thus potentially prove to be clinically useful for the treatment of ER-negative breast tumours that are typically unresponsive to traditional tamoxifen hormonal therapy."
