Throat Cancer Symptoms and Signs

Alterations in the timbre of speech. When the larynx is affected by cancer, it will obviously change the pitch and timbre of your voice. This is because the voice-box and the vocal cords together are what actually create the sound of your voice. As the dimensions of the throat change, and as the tumor perhaps puts pressure on the voice-box or on the vocal cords themselves, the sound of your voice is obviously going to change as well. Think of your throat and voice-box as a sort of wind instrument. As the dimensions of the instrument change, so also does the sound of the instrument.
