I kept taking estrogen, (but not the progesterone) and 13 years later had
breast cancer. I hold no one to blame because of the
estrogen. Most reports say that
estrogen alone does not cause breast cancer, but if one does get the cancer, the estrogen feeds it and makes it grow faster. Guess that is what happened to me. My cancer showed up between yearly mammograms. It was aggressive lobular, 5 CM , 14 nodes positive, making it stage 3. I am in treatment now (Chemo) and doing fine.
