Just a little about me. I m 62, 100 percent estrogen positive, 17 lymph nodes positive, bilateral mast, and cancer has returned sitting on the bones. I m taking tamoxifen and arimidex IM. I ve read nothing but negative things about arimidex. I don t want to have further health issues where I can t care for myself and spouse, who has polio. Do you think this is the drug of choice?
