Bone density scan

I am never quite sure if it's charting against the norm for someone your age or, as my oncologist suggests, against a constant baseline, which is about a 30 year old! It really needs a specialised explanation. I have got better at reading my own although the last one confused me. But I had read it correctly - some things are a bit worse, which is to be expected between my age and Femara, but some parts of me have significantly improved. Go figure!
