What Are Vocal Cord Polyps and Nodules?

Vocal cord polyps and nodules are both types of benign (noncancerous) lesions that form on the vocal folds and make the voice low, hoarse or breathy.

Polyps are more common in men than women and are almost always due to either chronic or acute overuse of the voice. Polyps can range in size and shape—from a blister to stalk-like growth—but they are generally found on just one side of the vocal fold.

Vocal nodules are often common among professional singers. They grow in pairs on the parts of the vocal cords that meet and vibrate when you are speaking or singing. They are usually small and resemble a callous.
