Worried symptoms could be sign of throat cancer

Hello there. I have a few symptoms, had chronic cough before, but that was gone.... I have quite a few scans coming up. all in all weird that no one included me looked at my throat for years. So a couple of days ago I found one of my tonsil somewhat swallen, and that thing is still there. Yes I was a smoker for almost 10 years, recently quit... I probably will contact my GP tomorrow, until then I just wonder if anyone can tell me... anything
