@pinkfish66, I'm so sorry to hear about your trials and tribulations in trying to advocate for your care. I think you are doing the right thing with contacting the ombudsman. Please contact them again and tell them what happened yesterday. You need medical attention. Can you reschedule your appointment with the oncologist? Or ask the ombudsman to mediate with another oncologist?
Staging requires different pieces of information. It is common that staging is not assigned until after surgery or a biopsy, along with other imaging studies and tests.
