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.
Nasopharyngeal cancer begins in the nasopharynx — the part of your throat just behind your nose.
Oropharyngeal cancer begins in the oropharynx — the part of your throat right behind your mouth.
Hypopharyngeal cancer (laryngopharyngeal cancer) begins in the hypopharyn the lower part of your throat, just above your esophagus and windpipe.
Glottic cancer begins in the vocal cords.
Supraglottic cancer begins in the upper portion of the voice box.
Subglottic cancer begins in the lower portion of your voice box, below your vocal cords.
