The difference with seeing an oral surgeon and an ENT is that an oral surgeon can do a biopsy and identify it as cancer or not, for the kind of care and treatment needed if you get a diagnosis of cancer - you must see an ENT - preferably one at a ccc or at least with major experience with oral cancer. So ultimately if you go to an oral surgeon, get a positive dx - then you have to wait for a referral then get an appointment with an ENT anyway. This could take some time - whereas if you are seeing an ENT from the outset, you're already where you need to be. Take care and best of luck with everything.
