Increased phytoestrogens commonly found in dietary soy may modify the risk of some types of breast cancer, according to findings presented at the Ninth Annual AACR Frontiers in Cancer Prevention Research Conference, held Nov. 7-10, 2010.
Anne Weaver and colleagues evaluated 683 women with breast cancer and compared them with 611 healthy women. Dietary data patterns were observed using a food frequency questionnaire and isoflavones were measured as a dietary, rather than supplemental, intake. Isoflavone (as for as my knowledge goes, above two isoflavones- see structures are present in soya) intake was divided into three groups. Those women with the highest isoflavone intake had an approximately 30 percent decreased risk of having an invasive breast tumor, and an approximately 60 percent decreased risk of having a grade 1 tumor. Among premenopausal women, the highest intake of isoflavones had a 30 percent decreased risk of stage I disease, a 70 percent decreased risk of having a tumor larger than 2 cm, and a 60 percent decreased risk of having stage 2 breast cancer. These connections were not seen among postmenopausal women...
