A second or third opinion is always beneficial. Massachusetts Eye and Ear, General Mass are top hospitals. Top CCC choose the patient, you don't choose them, especiallly in the recurrence setting, and if treated elsewhere. MSKCC radiology told me not to bother coming in for a consultation in 2012 for a recurrence! I went elsewhere, and had three more neck dissections, two internal radiation, and three external beam radiation treatments, one which was Proton Therapy after that!
MSKCC is top in cancer #2, #43 in ENT, still excellent, but others are rated better performing in ENT, as well as many others hospitals being the same. I look at their Cancer and ENT ratings, plus others.
