Paranasal Sinus Tumors
Cancerous tumors rarely occur inside the nose (nasal cavity) or in the paranasal sinuses (a group of air-filled spaces near the nasal cavity).

Scientists don’t know the cause. But we know that people who smoke are more likely to get sinus or nose cancer. So are people who work near certain types of chemicals. Studies show that men are more likely to get nose and sinus tumors than women. The condition is found most often in people who are in their 50s and 60s.

Any of the cells that make up the layer of mucus-producing tissue in the nose and sinuses can become cancerous. Other types of cells in the nose include bone and cartilage cells that can also become cancerous. Each type of cancer behaves differently.
