90% of cancer patients are treated at community hospitals, and some may be a Comprehensive Cancer Center or Cancer Center having top doctors, state of the art technology. Any place can be called a CCC or CC for that matter. There is no trademark, qualifications or restrictions for its use. There are ones designated by NCI, and NCCN, and as Christine mentioned, not all are equal. As far as NCI, some may have qualified for one cancer, but not all, and it has do more with grant money, meeting other qualifications, and not the outcome of any cancer treatment. and some may have even used their clout to get a designation. Then there is the listing themselves, there are 26 or so NCCN designations, and almost 50 on the NCI approved list, maybe I have it backwards, but about 25 are not on both listings or more, although some may just do research, but otherwise, why? I guess you have to look further if it truly is a CCC or CC, how obtained, patient outcome, who they really serve, and probably goes deeper than just a CCC or CC designation. Also, I was treated at two large high volume world renowned CCC for HNC, one community hospital, none which are on the NCI or NCCN listing, and see some other top rate CCC in NYC that aren't either, then some unheard centers are...makes you wonder?
