Laryngeal cancer refers to an abnormal growth of tissue in the larynx (voice box that holds the vocal cords and forms an air passage to the lungs). This growth develops when the cells in the larynx divide uncontrollably and produce extra tissue to form a tumour. Laryngeal cancer can occur on, above or below the vocal cords. It is a common head and neck cancer in Singapore and is strongly linked to smoking.
There are 3 types of laryngeal cancer:
- Glottic cancer that affects the vocal cords
- Supraglottic cancer that affects tissues above the vocal cords
- Subglottic cancer that affects tissues below the vocal cords
