I have had some osteopenia for years but no prolia yet. My oncologist has offered even though I do not have osteoporosis but as I am very close to the end of 10 years of Letrozole, I think I will hang out. My main concern with prolia is the possible need to stay on it once started - at this stage, I am in the mood for reducing substance ingestion!! We’re all different - it may still be a good idea in your case but it’s worth asking about how long, staying on it indefinitely or not, avoiding any problems with dental treatment (you need to have treatment when you are at the end of a cycle I believe) or any other matters you may want to take into consideration. Best wishes.
