Question: How to diagnose Nasopharyngeal Cancer ?
Answer: Tests that examine the nose and throat are used to detect (find) and diagnose nasopharyngeal cancer. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as swollen lymph nodes in the neck or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.    -   Neurological exam : A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a persons mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam.    -   Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue sample is removed during one of the following procedures:               -  Nasoscopy : A procedure to look inside the nose for abnormal areas. A nasoscope is inserted through the nose. A nasoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.       -  Upper endoscopy : A procedure to look at the inside of the nose, throat, esophagus, stomach, and duodenum (first part of the small intestine, near the stomach). An endoscope is inserted through the mouth and into the esophagus, stomach, and duodenum. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples. The tissue samples are checked under a microscope for signs of cancer.             -   MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).    -   CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.    -   PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. PET scans may be used to find nasopharyngeal cancers that have spread to the bone. Sometimes a PET scan and a CT scan are done at the same time. If there is any cancer, this increases the chance that it will be found.    -   Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.    -   Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:               -  The number of red blood cells, white blood cells, and platelets.      - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.      - The portion of the blood sample made up of red blood cells.              -  Epstein-Barr virus (EBV) test: A blood test to check for antibodies to the Epstein-Barr virus and DNA markers of the Epstein-Barr virus. These are found in the blood of patients who have been infected with EBV.    -  Hearing test: A procedure to check whether soft and loud sounds and low- and high-pitched sounds can be heard. Each ear is checked separately.
