Nasal cavity and paranasal sinus cancer

The nasal cavity is the large, air-filled space behind the nose. Paranasal sinuses are small air-filled spaces at the front of the skull, and surrounding the nasal cavity. They are found on the cheeks (the maxillary sinuses), above the eyes (the frontal sinuses), between the eyes (the ethmoidal air cells or sinuses) and behind the ethmoidal aircells (sphenoid sinuses). Nasal and paranasal cancers are relatively rare. The most common location of paranasal sinus cancer is the maxillary sinus. The symptoms of nasal and sinus cancer are similar to viral or bacterial infections, such as the common cold or sinusitis, and include; a persistent blocked nose, which usually only affects 1 side, nosebleeds, a decreased sense of smell and persistent mucus running from the nose or down the throat.
