Hi Karen,
I can't offer any further assistance here than the other ladies have, I am sorry. I have er+ secondary bc with bony mets. I have had radiotherapy this time (although had chemotherapy when I was diagnosed with early bc in 2003).
Currently I am taking Everolimus & Exemestane (similar to your Mum) and it seems to be working - due back to see my oncologist in a few weeks for my quarterly visit so will find it then. This is my first quarterly visit, prior to that it was monthly.
I am also on denomosaub - bi-monthly. This dosage can be amended accordingly depending on your Mum's calcium readings. Initially I was on this monthly but my calcium levels dropped significantly and ended up having a little stay in hospital.
As distance can be an issue here, maybe you could find out when your Mum's next appointment with her oncologist is and perhaps ring the rooms the previous week to check if you can be in a "conference call" when your Mum is in with her oncologist. That way, you are able to ask any questions that your Mum may not think of - another set of ears is always handy.
My very best wishes to both you & your Mum. My Mum had bony mets and lived 200 km's away. There were times when I was able to make some appointments but most of the time I could not. It is so difficult trying to support your Mum from a distance and you are an amazing daughter.
