Hi, there!
I would suggest really pushing to see that ENT very soon. Someone with your symptoms should not wait around a month. Strings need to be pulled to get you in much sooner, if not just for your piece of mind. Like Christine said, please seek out an ENT (otolaryngologist)that specializes in head & neck oncology (cancer).
Have you received any results from your other tests, such as the X-ray or Upper GI series?
I am not saying these things to alarm you. It's just that IF it is oral cancer, it's not something where you can afford time to wait to see a specialist.
Here's to hoping that it's nothing serious. We are all here to help and support you through this. Please keep us posted and best of luck to you!
