The paranasal sinuses are the aerated openings within the skull. These cavities, or sinuses, are lined by tissue to warm and humidify the air we breathe.
Sinus cancer is rare in western countries, but more common in countries such as Japan or South Africa. Men are twice more likely to be diagnosed than women.
Causes of Sinus Cancer
Like many form of cancer, the exact cause is unknown. People who use snuff for many years, or those who work in the wood or furniture industry and are exposed to wood dust, are more likely to develop paranasal sinus cancer. Smoking has also been found to increase the risk of developing cancer in this area of the body.
Signs and Symptoms of Sinus Cancer
Symptoms from sinus cancer depend on which sinus is involved. Obstruction of the sinus, with the accumulation of fluid, can produce pain
behind the nose or in the upper teeth. Swelling around the eyes may also occur. Numbness of the cheek, upper lip, upper teeth or side of the nose occurs. Persistent nosebleeds, headaches, or double visiond can occur from sinus cancer. Obstruction of the airways frequently produces an alteration of speech.
These symptoms may occur due to conditions other than cancer, and most people with these symptoms will not have paranasal sinus cancer. However, like most cancers, paranasal sinus cancer is most likely to be cured when diagnosed at an early stage.
