Although rare in the United States, paranasal sinus cancers are more common in Japan and among the Bantu people of South Africa. Doctors are not sure what causes these cancers, but they are more common among people who smoke tobacco or regularly inhale certain types of wood and metal dust. Human papillomavirus (HPV) and Epstein-Barr virus (EBV) may sometimes play a role. Doctors do not think chronic sinusitis causes these cancers.

Symptoms of Paranasal Sinus Cancer
Diagnosis of Paranasal Sinus Cancer
Doctors do imaging studies (typically computed tomography and magnetic resonance imaging) to locate the tumor and describe its extent. To confirm the cancer, a doctor will do a biopsy by removing some tissue and examining it under a microscope. Doctors use a flexible viewing tube called an endoscope to see, biopsy, and sometimes remove a tumor.
Prognosis of Paranasal Sinus Cancer
Treatment of Paranasal Sinus Cancer
Doctors treat paranasal sinus cancer with a combination of surgery and radiation therapy. Recent advances in surgical techniques have allowed doctors to remove some tumors completely through the nose using an endoscope. This can spare uninvolved parts of the face (such as the eye), resulting in better appearance and function after surgery. Radiation therapy is given following surgery if the tumor is likely to recur. Doctors may use radiation or chemotherapy as initial treatment when surgery would be ineffective or too difficult for certain tumors.
