Zero: Nasal polyps are not cancerous, but they multiply constantly and act as space occupying masses in the sinuses and nasal cavities.

Very rare: Cancer arising from a true nasal polyp whether unilateral or bilateral is not common. What should be considered with unilateral polyposis is a fungal infection. Unlike polyps of the colon, nasal polyps very rarely become malignant.
