Lakehouse,
Welcome to OCF...my first thought is to get on the phone to your oncologist and get a referral to another ENT...I can tell you right now - with what we go through no one should have to put up with a doctor they are uncomfortable with or don't have faith in. I switched after my radiation and the doctor's office even called and wanted me to come back. Guess the thought of missing out on all that money for monthly checkups got to him.
I don't know about doctors where you are, but you might have more faith and confidence in an ENT Oncologist. They are used to dealing with scared and concerned people. And know more of whatto look for regarding reoccurence.
When you find your new doctor have them call for your records. Or ask you oncolgist to forward them. That way you don't have to deal with it.
Good luck & take care,
Dinah
