Nasal and sinus cancer is a rare cancer that starts in the space behind your nose (nasal cavity) or in your sinuses.
The nasal cavity and sinuses help with your breathing and your sense of smell. They also help protect your airways from infection.
How serious nasal and sinus cancer is depends on whether it has spread to other parts of your head and neck, or to other parts of your body.
Nasal and sinus cancer is usually treated with surgery. Radiotherapy and chemotherapy can also be used.
