No, it's a good and fair question, one that I have asked myself. I was put on tamox/hormone therapy because (1) I am PR+23% (there are studies that say PR is as important as ER in being hormone responsive, and (2) (and this is the one I'm not sure I "get") I was pregnant at diagnosis, so she thinks it's safer to treat me as "if" I were strongly ER+. I'm not sure I get that, since I would think pregnancy would exaggerate the ER status, but I just took it at face value. I figured, at best, tamox could help, at worst, it would do me no good.
Now I read that it is could interact with her2 to potentially give me a worse prognosis....
