that can be used for patients with nasopharyngeal carcinoma. These three treatments are radiation therapy, chemotherapy, and surgery. Although there are currently three treatment methods, there are clinical trials taking place that may develop more effective treatments for NPC. A clinical trial is research study that works to develop new treatment techniques or to gain more information about or improve current methods. If an effective treatment comes out of the clinical trial, then this method may become a new standard treatment method. During the course of, or following, treatment, tests may be done in order to determine if the treatment is working, or if treatment needs to be dropped or changed. Tests that are done after treatment to determine the condition of patient after completing treatment are called follow-up tests and tell the doctor if the patient's condition has changed or if the cancer has come back.

cancer site. A mesh mask is used on the patient in order to keep their head and neck still while the machine rotates to send out beams of radiation. In undergoing this kind of treatment, healthy cells may also be damaged during the process. Therefore, there are 2 other forms of radiation therapy that decreases the likelihood of damaging nearby healthy cells: intensity-modulated radiation therapy and stereotactic radiation therapy. Intensity-modulated radiation therapy (IMRT) uses 3D images of the size and shape of the tumor to then direct thin beams of radiation at different intensities from multiple angles. In stereotactic radiation therapy, radiation is aimed directly at the tumor. In this therapy, the total amount of radiation is divided into smaller doses that will be given over the course of several days.

into a vein or muscle. In this method, the drug circulates through the blood system and can reach cancer cells throughout the body. Regional chemotherapy is when chemotherapy is administered directly into the cerebrospinal fluid, an organ, or a body cavity, for example, the abdomen. In this way, the drugs will mainly affect cancer cells in that area. However, the type of chemotherapy that is administered to the patient depends on the type and stage of the cancer. Additionally, chemotherapy can be used as an adjuvant therapy after radiation to lower the risk of recurrence in the patient. If given after radiation, chemotherapy can be used to kill any cancer cells that may have remained.

Additional symptoms of NPC include facial pain or numbness, blurred or double vision, trouble opening the mouth, or recurring ear infections. If the ear infection does not present with an upper respiratory tract infection, then an examination should be done on the nasopharynx. This is due to the fact that, in adults, ear infections are less common than in children. Signs and symptoms related to the primary tumor include 235:(EBV). The Epstein-Barr virus is one of the most common viruses. 95% of all people in the U.S. are exposed to this virus by the time they are 30–40 years old. The World Health Organization does not have set preventative measures for this virus because it is so easily spread and is worldwide. Very rarely does Epstein-Barr virus lead to cancer, which suggests a variety of influencing factors. 589:
Using radiation therapy as a cancer treatment method depends on the type and stage of cancer; however, internal and external radiation therapies can be used to treat NPC. If external radiation therapies are being aimed at the thyroid, then this could affect the way the thyroid works. For that reason,

More importantly, EBV DNA levels appear to correlate with treatment response and may predict disease recurrence, suggesting that they may be an independent indicator of prognosis. The mechanism by which EBV alters nasopharyngeal cells is being elucidated to provide

Chemotherapy works as cancer treatment by using drugs that stop the growth of cancer cells, by either killing the cells or preventing them from dividing. This kind of therapy can be administered systemically or regionally. Systemic chemotherapy is when the chemotherapy is taken orally or is injected

Surgery can be used as a method to determine whether there is cancer present or to remove cancer from the body. If the tumor does not respond to radiation therapy, then the patient may undergo an operation to have it removed. Cancers that may have spread to the lymph nodes may require the doctor to

Type 3 is most commonly found among younger children and adolescents, with a few type 2 cases. Both type 2 and 3 have been found to be associated with elevated levels of Epstein-Barr virus titers, but not type 1. Additionally, type 2 and type 3 may be followed with an influx of inflammatory cells,
