Laryngeal Cancer (Cancer of Larynx)

Cancer Types - Laryngeal Cancer (Cancer of the Larynx)

What is laryngeal cancer?

Laryngeal cancer includes cancerous cells found in any part of the larynx, which consists of the glottis, the supraglottis, or the subglottis.

The larynx, often referred to as the voice box, is a two-inch long tube-shaped organ located in the neck at the top of the trachea (windpipe). The cartilage in front of the larynx is sometimes called the Adam's apple.

The vocal cords (or vocal folds) are two bands of muscle that form a V shape inside the larynx.

The area of the larynx where the vocal cords are located is called the glottis. The area above the cords is called the supraglottis, and the area below the cords is called the subglottis. The epiglottis is a flap at the top of the trachea that closes over the larynx to protect it from food that is swallowed into the esophagus.

Breath enters the body through the nose or mouth, and then travels through the larynx, trachea, and into the lungs. It exits along the same path. Normally, no sound is made by the vocal cords during breathing or exhaling.

When a person talks, the vocal cords tighten, move closer together, and air from the lungs is forced between them. This makes them vibrate and produces sound.

Approximately 12,400 people are expected to be diagnosed with laryngeal cancer in the U.S. in 2012. Close to 3,600 deaths are expected to occur in 2012, reports the American Cancer Society.

How is laryngeal cancer diagnosed?

In addition to a complete medical history and physical examination, the doctor may carefully examine the neck to check for lumps, swelling, tenderness, and other changes.

Two types of laryngoscopy may be performed:

A biopsy, removal of a sample of tissue to be evaluated under a microscope by a pathologist, may also be performed.

If cancerous cells are found, imaging procedures may be used to determine the extent, or stage of the cancer.
