Curvature comes from fractures resulting in lower bone density. What are your DEXA scores?

I did 5 years of letrozole and my docs did not want me on Reclast or Zometa (same med) due to other health issues. I already had pretty severe osteoporosis when I started, and three old fractures from a traumatic fall.

I did lose bone density and due to COVID was late in starting Tymlos, a bone-builder and did have some lumbar fractures.

But Tymlos has returned my bone density to pre- cancer levels in two years of treatment.

So one option is to monitor your bone density and do Tymlos later. One caution: Just as with menopause, I lost maybe 10% bone density when I started letrozole but then it levelled off.
