Do the breast enhancement pills "breast actives" cause breast cancer or uterus cancer?

Don't use: I've never seen any scientific literature or patient studies that show any real improvement from these types of products. I think a consultation with a board certified plastic surgeon is the right place to start if you want to enhance the size of your breasts.

Unclear: I would advise against taking these.

Who knows?: Don't risk it! there is no safe way to grow or reduce breasts... Whether with supplements or medications. Augmentation with a plastic surgeon is the only safe way.
