Why can't your mom switch Doctors?

Even if she placed herself in hospice, one is always allowed to change one's mind.

Has your mother been disheartened? It may be an effect of medication.
Is she now being overmedicated? Is she "herself"?

Some (very few) here have relatively "happily" given up. Sheila always struck me as a fighter except when faced with the decision as to whether/how to radiate her brachial plexus, when I felt she didn't explore her options as vigorously as I felt she should have (but who am I to have an opinion, really!)
Since I am not qualified to give advice I never expressed mine regarding that choice, but kept posting more literature to review/ questions to raise

I wish her and you the best. Let us know if there is anything any of us can do eg. recommend another oncologist close to you, give info re getting into/out of hospice, etc
