Au Contraire!: Chemistry is a foreign language too, worse when used in drugs. This cmpd has an additional -oh group on the steroid rings, so cleave it an you get Estradiol - pure estrogen. Contraindicated in people with er + tumors, i.E makes tumors grow. It is proposed as an alternative to prempro (conjugated estrogens and medroxyprogesterone) for thos with severe hot flashes, and not at high risk for breast cancer.

It may: There are three main types of estrogen, estriol is the weakest of the three and there are reports that it is protective for breast cancer. It is the breakdown products of the other estrogens(estradiol , estrone) that can increase the risk of cancer. These metabolites can sometimes be affected in a positve way by diet (eg, brocolli).
