BOT is not usually able to be seen. Most BOT patients have no symptoms at all which is why its normally not caught until the later stages. BOT cancer is not like other oral cancers as its deep in the throat. Its not at all like the for example the inside of a persons cheek is easily viewed.

Ive seen everything you have gone thru as far as tests go and at this point I can only ask you to ask yourself a question. Will you ever be able to trust the doctors who have examined you and given you tests? From what you describe, you do have something going on. What it is, I couldnt even begin to take a guess at. The only thing I can suggest is to see your family doctor and ask for a complete physical. It could be any number of things going on besides OC which only a medical professional would be able to detect.

I wish you all the very best with this! Honestly, I dont think after all the tests you have been thru that you have oral cancer. But remember, I am not a medical professional and the other members here arent either. Sometimes in life you just have to put your trust in others as in the doctors who have already checked you out.

Best wishes with everything!
