What are the symptoms of laryngeal cancer?
Signs and symptoms of laryngeal cancer include a sore throat and ear pain. Tests that examine the throat and neck are used to help diagnose and stage laryngeal cancer. Certain factors affect prognosis (chance of recovery) and treatment options.
Where is 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.
Where does cancer spread?

Can you get laryngeal cancer from drinking too much alcohol?
Laryngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the larynx. Use of tobacco products and drinking too much alcohol can affect the risk of laryngeal cancer. Signs and symptoms of laryngeal cancer include a sore throat and ear pain.
External beam radiation therapy
During external beam radiation therapy, a machine directs radiation through the skin to the tumour and some of the tissue around it.
3-D conformal radiation therapy (3-D CRT)
3-D conformal radiation therapy (3-D CRT) delivers radiation beams of equal strength to the tumour from several different directions. This can decrease the radiation damage to normal tissues and increase the radiation to the tumour.
Intensity-modulated radiation therapy (IMRT)
Intensity-modulated radiation therapy (IMRT) delivers radiation beams of different strengths directed at the tumour from several different directions. This method shapes the treatment beams very precisely and allows the dose of radiation to be adjusted for different parts of the treatment area.
