My understanding is that AIs cut the possibility of recurrence by 60%. My oncologist- world renowned- begged me to take Anastrozole and to contact her immediately w discomfort. She said she has an arsenal of options to fight bad side effects and other AIs to try. I’m 1A IDC er and pr + her2 neg no lymph nodes and Oncotype = 0. I am 52. I paid attention to my symptoms before taking it. Joint pain etc. I take it at night bc it makes you tired. It’s fine. I guess I’m lucky. But like the other ppl say I take it bc it so reduces the risk of recurrence. In fact many recurrence stories are ppl who did not take it.

My sister after my diagnosis was told she had a 27% chance of getting BC. We have no genetic component. She was told to start Anastrozole as well. She is not noticing much — a bit more emotional. But otherwise ok.

I think my oncologist has see. The very worst and knows how effective AIs are. I was going to do whatever needed to make it work. My 2 cents.

Good luck to you!!
