Cancer of the paranasal sinus and nasal cavity is a disease in which cancer (malignant) cells are found in the tissues of the paranasal sinuses or nasal cavity.
This type of cancer most commonly starts in the cells that line the oropharynx. Much less often, cancer of the paranasal sinus and nasal cavity starts in the color-making cells called melanocytes, and is called a melanoma. If the cancer starts in the muscle or connecting tissue, it is called a sarcoma. Another type of cancer that can occur here, but grows more slowly, is called an inverting papilloma. Cancers called midline granulomas may also occur in the paranasal sinuses or nasal cavity, and they cause the tissue around them to break down.
The chance of recovery (prognosis) depends on where the cancer is in the sinuses, whether the cancer is just in the area where it started or has spread to other tissues (the stage), and the patient’s general state of health.
Our patients with paranasal cancer are treated at the Moores Head and Neck Cancer Unit. See the Head and Neck Cancer Unit for more information.
