Vocal cord nodules are growths that form on the vocal folds. They are benign- not cancerous. When you use your voice the wrong way, your vocal cords close together abruptly and over time swell. Over extended periods, the swelling can get harder, like a callous. These nodules can get larger and stiffer if your vocal abuse continues.
It is not beneficial for these nodules to be surgically removed, but voice therapy is recommended to change the way you are using your voice to eliminate or reduce the size of the nodules. You may experience a hoarse, breathy voice quality when you have nodules and feel vocal fatigue following periods of talking. However, fatigue may vary depending on the size of the vocal nodule. You may also experience a rough, raw, scratchy sensation in the throat area.
