Dear Expert,
I'm an old woman and I had a tumor in my one breast.I had radical mastectomy and my ER/PR test is negative . I was told hormon therapy is not effective to me because I am hormon negative receptor. Also I can't take chemotherapy . Now is taking an AI like Arimidex useful or necessary for me? If yes is there any major side effects for old women like me to neglect it?
Thanks a lot.
