3. Changes in your voice
The American Cancer Society explained that the larynx produces sound for speaking, and it protects your airway when you swallow. The epiglottis and vocal cords close tightly when you swallow to keep food and fluids from entering your lungs. The vocal cords open naturally when you breathe and also. The vocal cords also move and come together to change the sound and pitch of your voice.
A tumor that develops in the vocal cords causes hoarseness or a change in the sound or pitch of your voice. You need to see a specialist if the hoarseness or change in your voice doesn’t go away within two weeks.
