From my experience it will be Reclast or Zometa (both zoledronic acid) which protect bones during treatment for breast cancer and also may have some protective effect against recurrence.

Prolia and Xgeva are denosumab but I don't know anyone on that along with aromatase inhibitors.

I would definitely watch the free Stronger Bone video by Kevin Ellis on YouTube before going to a doctor to just be put on the dangerous bisphosphonates !! You will be way better informed. Kevin’s program has changed my journey completely.
