Hi there bethers answered your questions... But I will confirm what she said. My tongue was red... No ulceration, no white, just red. A biopsy of the area came back inflamed tissue - however if the ENT had taken the time to palpate he would have felt a lump inside my tongue. I thought it was scar tissue from where I'd had a piece of thickened skin removed ten years earlier, but no it was a tumor - definitely see someone who knows oral cancer. You can go see your oral surgeon again, but I'm not sure if it's a waste of time and money since he has already decided its nothing. Sometime because you're young the don't ntertain the idea (it's an old mans cancer usually involving heavy smokers and drinkers) Ipoint in fact I met with my SO on Monday, he sent his fellow in to examine me (a new guy from Switzerland - ) an the first words out of his mouth were - so how many cigarettes do you smoke a day? He almost fell off his chair when I told him I've never smoked, never drank, and I'm almost a vegan... It's those preformed beliefs that they sometimes have a hard time getting past. Hugs and good luck... And three hours is not fun, but it's worth it for your peace if mind and you're worth it.
