About stage and grade of nasal and sinus cancers

The stage of a cancer tells the doctor how far a cancer has grown or spread. It is very important because the stage often decides the treatment. The tests and scans that you have when your doctor is diagnosing your cancer will give you some information about the stage. But your doctor may not be able to tell you the exact stage until after you have surgery.

Different staging systems

There are different ways of staging cancers. The 2 main ways are the TNM system and number systems. Sometimes the stage of your cancer may sound a bit confusing. If you don’t feel you understand the stage of your cancer and would like to know more, ask your doctor or nurse.

The staging of nasal cavity and paranasal sinus cancers is extremely complicated. Staging systems have only been developed for maxillary sinus, ethmoid sinus and nasal cavity cancer. If you have cancer anywhere else in the sinuses your doctor will decide your treatment based on the size, location and type of the tumour you have.

The grade of your cancer

The grade of a cancer tells you how different the cancer cells are from normal cells when looked at under a microscope. Generally speaking, there are 3 or 4 grades ranging from most like normal cells to least like normal.

About the staging and grading of nasal cavity and paranasal sinus cancers

Cancer can develop in the nose and nasal cavity or in any of the several pairs of sinuses. The cancer may then spread to nearby tissue, the lymph nodes or other parts of the body.

The staging of nasal cavity and paranasal sinus cancers is extremely complicated. Staging systems have only been developed for maxillary sinus, ethmoid sinus cancer and nasal cavity cancer. If you have cancer anywhere else in the sinuses your doctor will decide your treatment based on the size, location and type of the tumour you have.
