Official title

Mammographic Density and Soy Isoflavones

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Soy consumption has been associated with reduced risk for developing breast cancer. Soy contains isoflavones which are weak estrogens. The roles of soy isoflavones in reducing breast cancer risk are currently unclear. Breast density has been considered as a breast cancer risk marker. We hypothesize that because isoflavones have estrogen-like activities, breast density and possibly bone density will be lower in women on soy-isoflavones.
