Yes, some oncologists have interests or more knowledge of specific cancers. My oncologist, also known to me as 'The Ice Princess", specialises in breast an bowel cancer. At the large Sydney hospital where I was treated, she saw her breast patients on a Tuesday, and the bowel patients on the Thursday. Now it happened that I had to see my rheumatologist on a Thursday, and that week was supposed to see her for my six month check up on the Tuesday. I tried to change my appointment from the Tuesday to the Thursday so it would mean only one trip to see both doctors. This was 2017, so prior to covid. The twit on the phone told me "Sorry, but Dr X only sees her breast cancer patients on a Tuesday...Thursdays are for her bowel cancer patients". A reminded her that it would be the same doctor in the same office, in the same department and that I would sit in the same chair. Could my file not be sent to her for the Thursday? "No, she explained to me very carefully, the breast and the bowel are in sepearate parts of the body"..duhhh..and then repeated her mantra about the days. So I threw her a curveball and asked her,'So, if I have both breast cancer and bowel cancer, both separate cancers at the different ends of my body, would I have to see her on the Tuesday for my breasts, and then return on the Thursday to discuss my bowel cancer?"...She replied with "I'm not sure...please hold while I go and ask someone..." Needless to say...I hung up then wiped the sprayed tea off my computer screen. But seriously, I hope your oncologist can get you sorted and that you get some rest from this bastard of a disease.
