A bone density test might reveal good news - I discovered when I had my first ever test before starting Letrozole that my bone density was excellent, way better than my age would suggest. It made the prospect of five years (it turned out to be ten!) on Letrozole easier to accept. My bone density has reduced since (partly ageing!) but knowing my bone density ‘bank balance’ was in credit helped a lot at the start and when the duration of medication was extended. Best wishes for yours.
