Laryngeal cancer starts in the lower part of the throat, also known as the larynx. The larynx has vocal cords and is responsible for helping us speak. It is otherwise known as the voice box. It also helps keep things out of the trachea like fluid and food and helps air get in and out of the lungs. Depending on where in the larynx the cancer is present, treatment options may vary. The larynx has three main parts: the supraglottis, the glottis, and the subglottis. The supraglottis is the area above the vocal cords; the glottis in the area that contains the vocal cords; and the subglottis is the area below the vocal cords.
