I had DCIS in 2007 in the right breast with lumpectomy and radiation. I then had IDC in 2018 in left breast with lumpectomy and radiation. No lymph node involvement either time. In September 2019 I found I had the CHEK2 genetic mutation and decided to have a bilateral mastectomy which I just had done in July 2020. I am curious about continuing with Anastrozole. I will see my oncologist soon and will speak to him about this, but am curious about what others’ experiences are. Are you still taking AIs? Since I am 70 and my bone health is very important to me, would switching to tamoxifen be beneficial or even an option? AIs can cause bone problems and I do not want to end up taking biophosphates. Does anyone relate to these concerns?
