Laryngeal Cancer: Causes, Risk Factors and Symptoms
Laryngeal Cancer: Causes, Risk Factors and Symptoms.
What is laryngeal cancer?
Laryngeal cancer is a type of throat cancer that affects your larynx. The larynx is your voice box. It contains cartilage and muscles that enable you to talk.
This type of cancer can damage your voice. When not treated quickly, it may spread to other parts of your body.
According to the National Cancer Institute, head and neck cancers account for 4 percent of all cancers in the United States. Survival rates for this cancer depend on its specific location and how early it’s diagnosed.
According to the American Cancer Society, 90 percent of people with stage 1 cancers of the glottis survive for five years or more. The glottis is the part of your larynx that contains your vocal cords.
In contrast, 59 percent of people with stage 1 cancer of the structures above the glottis, or supraglottis, survive for five years or longer. The supraglottis contains the epiglottis, which closes off your larynx when you swallow. It keeps food from entering your lungs.
