Nasal polyps are benign, non-cancerous inflammatory growths. They develop from the lining of your nose and sinuses in response to an inflammatory reaction, usually environmental allergies such as hay fever. Nasal cancer is rare. True nasal polyps do not turn into cancer, but cancers of the nose and sinuses can at times have an appearance similar to a polyp.
Brian Broker, MD, Allergy & Immunology, answeredNasal polyps are different than colon polyps. Colon polyps can be cancerous or pre-cancerous while nasal polyps are always benign. However, in unusual cases, certain cancers can form in the nose that look like polyps to the untrained eye.
Nasal papillomas, which typically look different than polyps, have a 13% chance of becoming cancers. These are typically removed to be sure.
There are other unusual nasal cancers that can mimic polyps. Its important to see an Ear, Nose and Throat doctor for any nasal polyps to determine if a biopsy is needed.
