Tests for Diagnosing Nasopharyngeal Cancer

If you are looking for some information on Nasopharyngeal cancer (NPC), you might be wondering how it is diagnosed and tested. Generally, the cancer is diagnosed when a person complains about a symptom like lump in the neck.

Nasopharyngeal cancer test or in other words a physical exam is performed to look for signs of the cancer. The doctor examines the neck area, head, throat, nose, mouth, facial muscles and lymph nodes of the patient. If he suspects that you have a tumor or a problem in your throat or nose, tests like MRI and CT are recommended to closely observe the neck and head area.

Exams for Nasopharynx

As it is located inside the head, and it cannot be seen easily, two types of special exams are performed for looking inside the Nasopharynx. First one is indirect nasopharyngoscopy. In this exam, the doctor uses lights and mirrors at the back of the throat to look into the nasopharynx and its surrounding areas. The second exam is direct nasopharyngoscopy in which a fiber optic scope called the nasopharyngoscope is used for looking into the nasopharynx line directly. It is one of the most commonly used exams for looking into Nasopharynx.


It is another exam that helps diagnose cancer. It involves removing cells from an abnormal area and examining them under a microscope.

Imaging tests

Imaging tests such as chest x-rays, CT scan, MRI scan or PET scans are performed to determine the structure of nasopharynx and its surrounding areas.

Apart from all these tests, blood tests are also performed. They are not used for diagnosing NPC, but they are helpful in telling if cancer has spread to other parts of the body.
