Hello, my fiance noticed a lump, about the size of a marbal, on his throat yeasterday on the left side of his adams apple. It is movable and has no pain , how ever, he says it feels weird when i mess with it... like a weird feeling in his next. He does smoke ... i dont like it but he will not quit for me. He is only 20 years old and i am highly concerned this could be cancer ... again the lump is on left side of his adams apple.. what do you think? He will be seeing a doctor tomorrow, im very worried!
