Thanks @sophiek55. Funny my oncologist thought 600 would be too high for me but tried it anyway. I am only on the second round of Kisqali tablets so hopefully my body handles it and I get a good response with it.
Wow @cranky_granny glad you oncologist was on to it. Sounds like mine. I fractured at T9 and the GP tried to tell me it was osteoporosis. That was in January this year. I had a feeling! I contacted my oncologist who did an mri. She repeatedly did mri's every 3 months and the bone mets finally showed up at T9 in my spine in July. The oncologist just kept hunting it down. She had continued to say to me ' it's not normal to fracture in your spine' and she kept ordering those scans until July when she ordered a pet scan and it confirmed this for me. I had lost a bit of weight in that 6 months too and I would look at myself in the mirror wondering if it was cancer. Well my gut feeling and the oncologist was right, it just took awhile to present itself. So onwards and upwards and scan to scan.
