What are Nasal Polyps?
Nasal polyps are noncancerous growths on the lining of the nasal passages and sinuses (small air-filled cavities located throughout the facial bones.) When the mucus membranes in the nose or sinuses become inflamed and enlarge over an extended length of time, a polyp forms. When polyps become large enough, they can obstruct nasal airways and sinuses, resulting in sinus infections and breathing difficulties.

- Sinusitis caused by an allergic fungus (an allergy to airborne fungi)
- Other infections, whether acute (short-term) or chronic
- Asthma
- An aspirin or other pain reliever allergy
