Many thanks @Romla. Yes I can get Prolia injections at the subsidised rate if I have osteoporosis or a bone density related fracture. As I have neither, I think I am willing to pay the full cost rather than wait for one of them to happen! As I have muttered before, proactive treatment seems contraindicated! Worth noting the dental issue, thank you. Mercifully my teeth seem pretty OK. Keeping my calcium intake up seems to have paid off and my cholestoral is fine. I am not committing to five years yet - 12 months at a time I think and my oncologist is happy with that. Onwards and upwards!
