My xerostomia is so bad that if I mouth breath during the night, when I get up in the morning I actually hack up phlem from my throat that has streaks of blood in it. Much of the time my oropharynx and throat have thousands of little paper like cuts on it and when I swallow anything that is citrus etc. it is like it's on fire. The tissue is just dired out to the point of actually cracking and bleeding.

Having said all that, I would still get a second opinion, and a scope. I would pick another guy for an opinion and get it checked out. U of P has a great faculty and that would be my choice in your area. At this stage of the game no one has used the C word attached to a firm biopsy report. Hold on to that and get another opinon as soon as you can from a place that has several docs that can look at you during the same visit. The Penn team would meet that goal.
