C30-C39: Malignant neoplasms of respiratory and intrathoracic organs

C32: Malignant neoplasm of larynx

Malignant neoplasm of the larynx relates to a group of conditions where cancer cells form in the larynx or voice box, a part of the throat. Laryngeal cancer starts in the cells lining the larynx and, if unchecked, can spread to other parts of the body. These conditions are mainly caused by long-term tobacco use and heavy alcohol consumption, which significantly increase the risk. Symptoms often include changes to voice such as persistent hoarseness, difficulty swallowing, persistent cough, ear pain, and a lump or sore that does not heal. The progression of these conditions can vary, but without intervention, they may severely impact the respiratory and digestive systems. This type of cancer may inhibit the normal functioning of the voice box, causing communication difficulties and affecting a person’s ability to breath and swallow.
