Welcome!
New York City has the largest concentration of top cancer centers in the country, and forget about top doctors! Just off the top of my head, and including some of the cancer centers I was treated at include:
NYU, Beth Israel which is now part of Mt Sinai but still seperate, Mt Sinai, NY Presbyterian, NY Eye and Ear, MSKCC, and others.
You’ve received good advise so far, and wish the best!
