cancer, laryngeal A malignant tumor of the voice box (larynx), which is located at the top of the windpipe (trachea). Cancer of the larynx occurs most often in people over the age of 55, especially those who have been heavy smokers. People who stop smoking can greatly reduce their risk. Hoarseness without pain can be a symptom of cancer of the larynx. The larynx can be examined with a viewing tube called a laryngoscope. Cancer of the larynx is usually treated with radiation therapy or surgery. Chemotherapy can also be used for laryngeal cancers that have spread.
