You must change doctor offices. You will never get a different doctor within this office as they will all stick together.
This may mean traveling to a different location or city for a doctor but hope is essential to the care and treatment of a person with cancer.
We just changed nuero-oncologists for my husband's GBM after getting incredibly insensitive care from a doctor and his entire office when we were not happy with their practically eliminating steroids during the middle of radiation therapy. Fortunately we live in the Boston area so we had other choices. I have since read that it is essential to maintain steroids during radiation, and my husband is now suffering the results of their elimination. He practically died this week from radiation encephelopathy due to this error. fortunately competent care saved him but he is now at a rehab cent and getting help, but not happy about it.
