breast cancer and infertility treatment

I had treatment about ten years ago. The reason I became suspicious is because I had started having menopause symptoms such as hot flashes, irritability. My breasts were very painful, both of them, all over. Shortly after these symtoms I felt a mass in my right breast (I have always done self exams). It grew very quickly (who knows how long it was growing before I felt it). I'm no expert, but I felt this was some type of hormonal issue which catapolted the breast cancer. I also have none of the other typical reasons for developing breast cancer except one. No family history, etc. I guess the only one I had was not ever having kids. Funny thing is that I had to have envitro because I developed Toxic Shock as a teenager which ultimately destroyed my reproductive system. Since my cancer treatment, all menopause symptoms have dissappeared. I haven't been able to get my records on which drugs I took. I know there was a shot I had I think 2x per day and something else. It was a tramatic experience. I have blocked it out. I really didn't like hearing that the reason I got breast cancer was because "I'm a woman". I'm a cause and effect person. I really need to know so I can prevent the cancer from coming back. Thanks for sharing.
