I had visits with a number of doctors, but my lead is my Uro/surgeon. When RT became an evident need, I added an RO for that, but the RO did not desire to be involved in any continuing treatment, and handed me back to the uro at the end of RT.
I have a medical oncologist, but he is happy with how my uro is handling things, and suggests that the office fees he charges would be wasted money in my situation. He is on record, and I can consult with him should I need to.
My GP sees me every six months, and gets copies of all of my medical activities.
So, do I sit in a room with a table of multiple doctors? No. Do I have a "team"? Only if I need a "team".
