Nose and Sinuses

What are paranasal sinus and nasal cavity cancers?

The paranasal sinuses are small hollow spaces in the bones of the head surrounding the nose. The nasal cavity is the hollow space inside the nose where air moves around during breathing. Paranasal sinus and nasal cavity cancer is a disease in which cancerous cells form in the tissues of these areas.

The most common type is squamous cell carcinoma, which forms in the thin, flat cells lining the inside of the paranasal sinuses and the nasal cavity.
