Nasal and sinus cancers

Cancers in the inside of the nose or sinuses are known as nasal or sinus cancers. This type of cancer is rare.

Patients may experience blocked nose, change in voice, swelling of the cheek, headache, pain or numbness in the cheek. The main risk factor for this type of cancer is smoking but may also be associated with inhalation of chemicals, metals and wood dust over many years.
