Throat cancer refers to cancerous tumors that develop in your throat (pharynx), voice box (larynx) or tonsils.

Your throat is a 5-inch-long muscular tube that begins behind your nose and ends in your neck. Your voice box sits just below your throat and is also susceptible to throat cancer. The voice box is made of cartilage and contains the vocal cords that vibrate to make sound when you talk. Throat cancer can also affect the piece of cartilage (epiglottis) that acts as a lid for your windpipe. Tonsil cancer, another form of throat cancer, affects the tonsils which are located on the back of the throat.
