I was on Ibrance on and off for 6 months. I had my first scan last week and my oncologist said it was a good scan and because I continued having problems with Ibrance she was taking me off. I’m currently only taking Letrozole 2.5 mg. I’m concerned that I’m only in that one medication. Is that a common form of treatment? I have stage 4 breast cancer that’s gone to my bones.
