Laryngeal Cancer
About Laryngeal Cancer
Laryngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the larynx.
The larynx is a part of the throat, between the base of the tongue and the trachea. The larynx contains the vocal cords, which vibrate and make sound when air is directed against them. The sound echoes through the pharynx, mouth, and nose to make a person's voice.
There are three main parts of the larynx:
- Supraglottis: The upper part of the larynx above the vocal cords, including the epiglottis.
- Glottis: The middle part of the larynx where the vocal cords are located.
- Subglottis: The lower part of the larynx between the vocal cords and the trachea (windpipe).
Most laryngeal cancers form in squamous cells, the thin, flat cells lining the inside of the larynx.
Laryngeal cancer is a type of head and neck cancer.
