Non-cancerous tumours of the nasal cavity and paranasal sinuses
A non-cancerous (benign) tumour of the nasal cavity or paranasal sinuses is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are not usually life-threatening, and they are typically removed with surgery. Non-cancerous tumours located in the nasal cavity and paranasal sinuses usually come back (recur).
There are a few types of non-cancerous tumours of the nasal cavity and paranasal sinuses.

Inverting papilloma is the second most common non-cancerous nasal cavity and paranasal sinus tumour. Inverting papilloma is a warty growth that is most common in men between the ages of 40 and 70. Research suggests that about 30% of cases of inverting papilloma are linked to an infection with the
This type of tumour is considered non-cancerous, but inverting papilloma is aggressive. It can destroy the surrounding bone or grow deeply into the tissues near the sinuses, including brain tissue.
Inverting papilloma can cause:
- blocked nose
- watery eyes
In 5% to 15% of cases, inverting papilloma may develop into squamous cell carcinoma (SCC), which is a cancerous tumour. Find out more about cancerous tumours of the nasal cavity and paranasal sinuses.
