I don't know how this post works-difficult. I hope this goes thru. I was on letrozole, anastozole & exemestane. All made me sick. They said my last test no malignancy. Dr. had me on exemestane 2x wk, wanted 3x. I outright quit. Didn't ask, told him. I'm 82, was totally wiped out, made my arthritis a lot worse it IS a poison. I'm getting all my follow up tests.
