Can you advise me what symptons to look for when diagnosing throat cancer.  Ive had a persistant dry tickly cough now for at least 2 months.   I havent had a cold or been ill in anyway, and Im a non smoker.  I am a 63 year old male.  Its not a constant cough, but persistant, and seems to be getting worse.  It doesnt wake me at night, just troublesome during the day.  My throat isnt sore or swollen.Thank you
Nagging cough is a warning sign for cancer, but it doesn't mean its 100 percent cancer, It's safe to get checked and rule out cancer. Other reasons can be allergy to some agent you got exposed to recently and constantly around it. Meet an ENT doctor and rule out cancer.
