You usually start by seeing your GP. They will examine you and might refer you for tests or to a specialist. If the tests show that you have a cancer, you have more tests to find out how big it is and whether it has spread. This is called staging.
There are some things you can do to get the most out of your GP appointment.
Your GP should arrange for you to see a specialist if you have symptoms that could be due to nasal or paranasal sinus cancer.
Screening means testing people for early stages of a disease before they have any symptoms.
You might have one or more tests to diagnose nasal and paranasal sinus cancer.
These tests find out the position of the cancer, how big it is and whether it has spread. They will help your doctor to decide on the treatment you need.
