For most, if not all, of the listed facilities, cancer treatment is by no means their only reason for existance.
Pete, In my opinion the biggest advantage I received from the CCC I was treated in is the coordination of care. Before being referred to the University of Chicago, I was the one who attempted to coordinate the EENT, Oncologist, Radiation Oncologist, dentist, etc. It was totally bewildering!
At a CCC these people are all working together, and more importantly, they meet regularly, usually at a "Tumor Board" to discuss your treatment and progress. I strongly believe that this approach contributed significantly to my success so far. Along with many others on this board, I cannot recommend this approach highly enough.
