Cancers that form in the tissues of the passageway within your nose are referred to as paranasal sinus and nasal cavity cancers. Nasal cancer begins in the nasal cavity, which is the space directly behind the nose where air passes on its way to the throat. Paranasal cancer begins in the paranasal sinuses — hollow, air-filled spaces in the bones around the nose. Both are considered types of head and neck cancers.
Several types of nasal and paranasal tumors exist. Your specific type will determine what course of treatment will work best.
Within the nasal cavity and paranasal sinuses are tissues that contain several different types of cells that include:
Various types of nasal and sinus cavity cancer can develop from these cells. The most common is squamous cell carcinoma, which forms in the flat cells that line the inside of the nasal area. It accounts for about half of cancers in these areas.
Other types of nasal cavity and sinus cancer that can develop include:
Knowing which cells they come from helps determine how fast the cancer will grow and what type of treatment will be needed.
There are several tests that help diagnose paranasal sinus and nasal cavity cancers.
After a diagnosis, it’s necessary to determine if cancer cells have spread .
Treatment may include a combination of surgery, radiation therapy, chemotherapy, and immunotherapy.
