what are polyps in the nose

Nasal polyps are soft, painless, noncancerous growths that develop in the lining of the nose or the sinuses. They are often shaped like teardrops and can form in groups. These polyps are associated with chronic rhinosinusitis, which is inflammation of the nasal passages and sinuses lasting 12 weeks or more. The exact cause of nasal polyps is not fully understood, but they are believed to be linked to long-term swelling and inflammation in the nose from allergies, asthma, or infection. They are more common in people with asthma, allergies, repeat infections, or inflammation in the nasal passages. Nasal polyps can lead to symptoms such as a blocked nose, breathing problems, loss of smell, and infections. Treatment options include medication, such as nasal corticosteroid sprays, and in some cases, surgery may be required to remove the polyps if they do not respond to medication. Nasal polyps are not cancerous, and they can be diagnosed by a doctor using a nasal endoscope or imaging scans of the sinuses.
