Rick, I am assuming you know what I'm about to say, but reading your story again, I thought I'd say it just in case you don't. You do not need to go through your ENT, or wait for his reommendation of who to go to, for the second opinion. Some comprehensive cancer centers have web pages you can go to as a patient to fill out a request for a second opinion---as simple as that. That's what I did (in my case, my ENT recommended I get a second opinion somewhere but I did the rest of the legwork myself).
