I would highly recommend that you don't consider soy products at all. That goes for anyone who has fibrocystic breasts or has undergone a recent breast biopsy.

Everyone should read this about Genistein, (one of phytoestrogens in PM and other products).

Also note that increased consumption of soy products reduces plasma concentrations of estradiol.

Genistein: does it prevent or promote breast cancer?

From pg. 702 Possible Anti-Estrogenic Effects of Genistein

Genistein has significant estrogenic properties in both in vitro and in vivomodels (Table1). Genistein binds to the estrogen receptor(ER), although its binding affinity is several-fold weaker than that of estradiol(30). Genistein can also activate a number of estrogen-responsive genes in vitro, including pS2 and c-fos (18,31). Furthermore, when administered at low doses, genistein stimulates the growth of ER-positive(ER+) breast cancer cells (18-20). Findings in other tissue systems support the estrogenicity of genistein. For example, genistein is uterotrophic in a variety of species, resulting in impaired reproductive activity and increases inuterine wet weights.
