I’ve just been diagnosed with osteoporosis (my T score is -2.9) and I’m 42. I was diagnosed with BC in July last year... I’m NED and on Zoladex and Exemastane. This is something I was not expecting....
Talk to your oncologist. You could have some bone strengthening treatments. You could have a spell off the current meds or even have those ones changed. Even off all meds you will still need to keep an eye off that osteo and make sure nothing else nasty develops in the future.
