If your dad's insurance permits, seek an appointment at Memorial Sloan-Kettering
in NYC (link is to the Make an Appointment page) or
its facility in Basking Ridge, NJ. In the U.S. News rankings, Sloan-Kettering vies with M.D. Anderson in Houston as the top cancer center in the country. As another poster here noted recently, you get only one shot at a first treatment of this disease, and you want it to be from people who have seen a LOT of oral cancer.
The quote below was posted by a relatively new OCFer after her husband was diagnosed with OC by an ENT. Since she lives in New York City, several people here encouraged her to get a second opinion at Sloan-Kettering. She posted this in mid-February after making an appointment there:
[quote=SusanW]The ENT guy said his practice (three guys) sees about one case of oral cancer a year. Sloan sees 3500. A bit of a difference. The strong message you guys sent me about where people should go is so important. I hope the word is out there.[/quote]
