Thank you for your wise words.
My dentist is sending me to an oral surgeon who will do a biopsy in his office on Thursday. I asked about an ENT cancer specialist, but we do not have one where I live. After reading stories here plus reputable sites on the Internet, if I do get a cancer diagnosis, I am going to go to the closest cancer center to me. My city doesn't seem to have the specialists for this type of problem.
Again, my thanks for the advice and support. This has really thrown me for a loop.
