Paranasal Sinus and Nasal Cavity Cancer
Nasal and sinus cancers
Nasal and sinus cancers affect the nasal cavity and the sinuses around the nose, which are known as paranasal sinuses. There are many pairs of sinuses in the area around the nose and cancer can develop in any of them. Cancer that affects the nasal cavity and the paranasal sinuses is known as nasal and paranasal sinus cancer. The area where the nose and throat meet is known as the nasopharynx; cancer that occurs in this area is known as nasopharyngeal cancer, which is different to nasal and paranasal sinus cancer. Nasal and sinus cancers are rare and only 450 cases of the disease are diagnosed in the UK each year.
