Laryngeal Cancer

Laryngeal cancer is a type of cancer that affects the larynx - an organ that plays an important role in breathing and communicating. It contains the vocal cords, which give us the sound needed to speak. The larynx is composed of three different parts:

• Glottis - the part of the larynx that contains the vocal cords
• Supraglottis - the area above the glottis
• Subglottis - area below the glottis

Cancer can develop in each of these three areas and are unique from one another. They each produce different symptoms, require different treatment methods, and vary in prognosis.
