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.
Nasal polyps @(Model.HeadingTag)>
Nasal polyps are the most common non-cancerous nasal cavity and paranasal sinus tumour. They are abnormal growths in the
Nasal polyps can cause:
stuffy, blocked or runny nose
loss of sense of smell
Most nasal polyps develop when allergies, infection or other conditions make the mucous membrane of the nose or paranasal sinuses inflamed. Nasal polyps may also develop in people with asthma.
Nasal polyps are usually treated when they start to cause symptoms. Treatments include nasal steroid sprays,
Inverting papilloma @(Model.HeadingTag)>
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:
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.
Because inverting papilloma can be dangerous and may become cancerous, doctors usually remove these tumours with surgery using an
