Sterinol-Moducare

I have high estrogen breast cancer and have read that taking a sterinol supplement will help balance the immune system.  Does this supplement mimic DHEA .(dehydroepiandrosterone) is it safe to take with medication to stop the production of estrogen.

Also is it safe to eat high levels of soy products with high estrogen breast cancer.

Dear survivor400,  The issue with soy is that it contains chemicals that are very similar to estrogens.  If the breast cancer is estrogen receptor positive, some of the treatments that are given work by blocking estrogen production.  By ingesting other estrogens, there is a theoretical concern that a person could be interfering with the therapeutic effect of reducing estrogen and, in fact, give the tumor the food it needs to grow.  It is not clear, however, that the types of plant estrogens found in soy and other foods are harmful to women being treated for breast cancer.  Oncologists vary in their opinions on this, but many do not restrict foods. Some do have concerns about dietary supplements that are not regulated by the FDA and may contain unknown amounts of estrogen-like substances.  Because these supplements do not require testing for safety or efficacy, it is unknown whether these might be helpful, harmful, or neutral. You should discuss your specific situation with your oncologist.
