Cancer of the larynx. Coloured 3D computed tomography (CT) scan of the neck of a patient with a cancer (orange) of the larynx. This is a view from inside the larynx, with the cancerous tissue forming the irregular shapes in the normally symmetrical structure. The larynx (voicebox) is the lower part of the throat, and forms part of the upper respiratory tract. Air from the mouth and nose passes through the larynx to reach the lungs. The larynx contains the vocal cords, and air passing out of the lungs resonates in the larynx to produce vocal sounds. Cancer of the larynx can be caused by smoking. Treatment involves removal of the cancerous tissue, with radiotherapy and chemotherapy.
