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.

Symptoms of paranasal sinus cancer result from the cancer pressing on nearby structures and include
Most people do not develop symptoms until the cancer is well advanced, because the sinuses provide room for an early cancer to grow without pressing on nearby structures.
Doctors do imaging studies (typically computed tomography Computed Tomography (CT) In computed tomography (CT), which used to be called computed axial tomography (CAT), an x-ray source and x-ray detector rotate around a person. In modern scanners, the x-ray detector usually... read more and magnetic resonance imaging) Magnetic Resonance Imaging (MRI) In magnetic resonance imaging (MRI), a strong magnetic field and very high frequency radio waves are used to produce highly detailed images. MRI does not use x-rays and is usually very safe... read more 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.
Doctors treat paranasal sinus cancer with a combination of surgery Surgery for Cancer Surgery is a traditional form of cancer treatment. It is the most effective in eliminating most types of cancer before it has spread to lymph nodes or distant sites (metastasized). Surgery may... read more and radiation therapy Radiation Therapy for Cancer Radiation is a form of intense energy generated by a radioactive substance, such as cobalt, or by specialized equipment, such as an atomic particle (linear) accelerator. Radiation preferentially... read more . 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 Chemotherapy Chemotherapy involves the use of drugs to destroy cancer cells. Although an ideal drug would destroy cancer cells without harming normal cells, most drugs are not that selective. Instead, drugs... read more as initial treatment when surgery would be ineffective or too difficult for certain tumors.
