Welcome to the forum. I'm sorry you have to deal with oral cancer. However, all of us here have dealt with it one way or another, so we know and understand what you're going through.

Since you only had the CT scan and PET scan on Friday, I would think the treatment should depend on those results rather than on the scope. So, you may have to prepare for a possible change of plans. I agree with Christine that you should consider a second opinion at a CCC. There the doctors work as a team and there are treatment protocols that they have to follow. You will probably benefit from other services there, such as a dietitian or counseling at any point if you need it.

When my husband was diagnosed, we were told that the timeline given by the government (I'm in Canada) for oral cancer patients was to get them to start treatment in six weeks. Those weeks actually flew by. We saw the radiation oncologist, the medical oncologist, the dental oncologist (all at the same hospital), had the teeth checked, mask made, and then the first treatment started. My husband was followed by a dietitian all through to make sure he was eating enough. I really can't think where else we could get that kind of service.
