I remember on my first wife's battle with cancer the Primary Care Physician we had said "I'm the quarter back on this one, I'll coordinate everything and all the other doctors" - such as oncologist, surgeon, radiologist, PT, etc.

Now this particular doctor has won awards aftrward for being caring and going the extra mile for his patients, he was doing "house calls" to the hospice my wife was in during her stay there. During one visit when it was finally evident the battle was lost, he broke down and almost started crying.

Anyway, the PCP was the one that took looked at all the facts, made a final suggestion/reccomendation after explaining all the options/consequences.

Sometimes when there's multiple doctors involved, it seems you kind of need a "referee"
