How Long Does It Take For A Nasal Polyp To Turn Into Cancer?

A nasal polyp is a sac-like non-cancerous tissue outgrowth which remains symptomless in most of the individuals. During multi-polyps, particularly large size tissue has several complications among patients which affects their quality of life(1).

Mass of tissue and fluid lesions may block the nasal passages and lead to respiratory problems. Frequent bacterial infection, loss of smell and taste, fluid discharge, migraine, pain around eyes, pressure in forehead and face are observed in nasal polyps. Severe inflammation must be treated immediately with nasal or oral corticosteroids and advanced condition endoscopy sinus surgery is recommended.

Extra growth of tissue lining the nasal cavity and paranasal sinuses are not melanomas, but they could still cause hitches among patients. It has to be closely verified by respiratory physicians and must treat earlier with medicine or surgery. Nasal Polyps is a non-cancerous tissue or benign tissue. They are pink in color, watery-discharge tissue growth that occurs within the nose and sinuses. They are not a precursor to cancer and there is no report till now on polyps and its risk of developing into cancer.

Whether Cancer Occur in Nasal Cavities?

Nasal cavity and sinus cancers are rare among the population. But, there is an exception in the USA and nearly 2,000 individuals suffer from these cancers each year(2). Most of them are geriatric population and particularly, men are affected more compared to women. Researchers found a genetic factor is a reason for causing such changes and cancer.

Nasal Polyps In Canines

The source of nasal polyps in canines is not clear, but clinical signs in canines with nasal polyps include sneezing, nasal discharge, epistaxis, and stertor (A stertor is a respiratory sound characterized by heavy snoring or gasping). In dogs, there was a strong clinical suspicion of nasal neoplasia(3). The word “cancer” denotes malignancy, but neoplasms can be subclassified as either benign or malignant.


Nasal polyps are not cancerous cells or it will not develop into cancerous form. No potential scientific evidence reported as of till date about its risk of developing to cancer. It is abnormal growth and chronic (long-lasting) inflammation in the nasal cavity or paranasal sinuses.
