For the past 3 weeks I have had a swollen tonsil just on the right hand side and cobblestoning at the back of my throat. I initially had ear pain and headache but that has gone and have also been on a 10 day course of antibiotics with no change. Really worried about tonsil cancer even though I know it is unlikely. I'm 19, female and have been a social smoker since I was about 16 but quit a couple of months ago. I used to get an itchy throat sometimes from smoking and a sore on the roof of my mouth from scratching which would heal in a week but come back sometimes if I smoked again. Could this have been a sign of oral cancer that I ignored? Can't stop thinking about it
