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.
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.
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).
Symptoms and Risk Factors for Laryngeal Cancer
Signs and symptoms of laryngeal cancer often include a sore throat and ear pain.
These and other signs and symptoms may be caused by laryngeal cancer or by other conditions. Check with your doctor if you have any of the following:
- A sore throat or cough that does not go away
- Trouble or pain when swallowing

- A change or hoarseness in the voice
Use of tobacco products and drinking too much alcohol can affect the risk of laryngeal cancer.
