Throat cancer refers cancer that develops in your throat (pharynx) or voice box (larynx).
Your throat is a muscular tube that begins behind your nose and ends in your neck. Throat cancer most often begins in the flat cells that line the inside of your throat.
Your voice box sits just below your throat and also is susceptible to throat cancer. The voice box is made of cartilage and contains the vocal cords that vibrate to make sound when you talk.
