Hi and welcome to OCF.

Queries like yours are common, and sometimes I feel like saying OMG thats a classic stage 5 uvulopalato cancer cluster! You're going to die by the weekend!!! Of course its no laughing matter, but if you google long enough thats what you'll find.

Oral surgeons are fancy dentists, ENTs treat cancers and the oral surgeon will probably just refer you to an ENT. The lump could be many things, most of them harmless. A biopsy is the definitive way if its cancer and what type it is. The positive side of oral cancers is it is relatively straightforward to do a biopsy with no more than a local.

Let us know how you go, and try to keep calm and stay off the internet. I'm fairly confident you'll survive the weekend
