Laryngeal cancer occurs when cancerous cells form on the tissues of the larynx, or voice box. The larynx contains the vocal folds. The vocal folds vibrate. This makes sound when air is directed against them. A person’s voice is heard when this sound echoes through the throat, mouth, and nose.
Your doctor will examine your throat for lumps. A procedure called a laryngoscopy may also be performed to look down your throat and view your larynx. Your doctor may need to do a biopsy and remove a small piece of tissue to test for cancer cells. A biopsy is the only way to know for sure if cancer cells are present.
