How long before throat cancer progresses, i have throat clearing for 2 years, not any worse than when it started, and never during sleep, very scared?

Get checked out!: Have you been diagnosed with throat cancer or are you worried you may have it? If this is a worry and not actually diagnosed, go to your doctor! if you had throat cancer for 2 years i think you'd be pretty sick by now, but check it out so you can stop worrying. This could be something as benign as a non-allergic rhinitis causing a drip in the back of your throat. Throat cancer would progress.
