My breast cancer was fed by hormones post-menopause, as are many breast cancers (80% I believe) so I hope people are thinking about family history, mammograms and maybe getting genetic testing before using hormones.

It isn't just people who already have cancer who need to worry. Just want to clarify that. We all have cancer cells in our body that our immune system takes care of most of the time- or so I have been told. Some of those cells may respond to the hormones and grow, if genetics or other factors are present.
