MSKCC was designed #1 this year for cancer by U.S. News Report Best Hospitals Some others others are in the top 50 for cancer, top 10 or 20 for ENT. Others top paces not mentioned are NY Presbyterian, Lenox Hill, Montifiore, to name a few.
Anyplace can be called a CCC or CC. There are no trademarks, qualifications or restrictions for its use. As far as NCI designations, some may have qualified for one cancer, but not all, and has to do more with grant money, meeting other qualifications, and not their outcome of any cancer treatment, and some may have used their clout to get a designation.
NCCN has their own criteria for inclusion, and some on this list, around 28, may not be NCI designated and vice versa, but many are on the U.S. News Report Best Hospitals.
