I am an 18 year old female with no history of smoking. As far as I can think back I’ve had a little piece of skin connected next to my uvula. It was small and the exact same color as the skin around it. I never felt or noticed it until I coughed and realized it was sticking to the roof of my mouth. Just recently, I was coughing to clear mucus out of my throat and I felt like something was stuck back there so I looked back and the piece of skin had detached from the uvula and was hanging right next to it. Since then I feel it every time I swallow and it seems appears larger then it was before. It’s making me gag all the time and I am really concerned as to what it could be. The only other abnormality I’ve noticed is that I had one small tonsil stone, which I don’t often get. I contacted my GP, but should I be worried? I’m paranoid about cancer.
