Thank you all....
I called around all morning and found an ENT who is also a surgeon who could do the biopsy right away if he needs to. My husband has an appointment for Monday morning. Much better than the family doc a week from Thursday only to be referred to a specialist! I couldn't find an oral surgeon who had any openings in the near future. It's the end of the year, and everyone wants to use up their insurance....
Thank you again for the advice, and I wish the best for all of you who are fighting this.
