What is laryngeal cancer?
Laryngeal cancer is a type of head and neck cancer that begins in the larynx or "voice box" where your vocal cords are. There are three parts of the larynx: the supraglottis, glottis, and subglottis. Cancer cells can begin to grow in any of these areas. People most at risk for this type of cancer are heavy smokers and heavy drinkers of alcohol.
Symptoms of laryngeal cancer
Cancer of the larynx often begins with dysplasia, a precancerous condition marked by abnormal development of cells. Dysplasia may advance to carcinoma in situ (CIS), in which cancerous cells are found in the lining of the larynx, but the cancer has not spread beyond this area. Cancer in this stage is still very treatable.
A person with laryngeal cancer may experience certain symptoms, such as:
- Difficulty breathing
- Difficulty or pain swallowing
- Ear pain
- Hoarse voice
- Lump in neck or throat
