Nasal polyps are growths that occur on the lining of the nasal passages or sinuses. They are usually noncancerous and can vary in size from small and unnoticeable to large enough to cause significant breathing problems. Nasal polyps are typically associated with chronic inflammation in the nasal passages, such as that which occurs with allergies or sinus infections.
If you suspect that you have nasal polyps, it is important to see a healthcare professional. They can perform a physical exam, including a nasal endoscopy, to confirm the diagnosis and determine the size and location of the polyps.
It is also important to manage any underlying conditions that may be contributing to the development of nasal polyps, such as allergies or sinus infections, to help prevent recurrence.
