What is nasopharyngeal cancer?
Nasopharyngeal cancer is a cancer that begins in the nasopharynx — the upper part of the throat, located behind the nose and above the soft part of the roof of the mouth, where the back of the nose meets the top of the throat. This area is tucked deep inside the head, near the base of the skull, the ear canals, and important nerves, which makes surgery there very difficult. That is why nasopharyngeal cancer is treated differently from most other head and neck cancers: radiation, usually combined with chemotherapy, is the main treatment rather than surgery. The disease is strongly linked to the Epstein-Barr virus (the same common virus that causes mononucleosis) and is more common in parts of Asia and North Africa, though it can occur anywhere. Early symptoms — a lump in the neck, a blocked or bleeding nose, ringing or fullness in one ear, or hearing changes — can be subtle. The good news is that nasopharyngeal cancer is very sensitive to radiation, and many patients are cured.
The main types
Doctors group nasopharyngeal cancer by where it starts and how it behaves:
| Type | What it means, simply |
|---|---|
| Keratinizing squamous cell carcinoma | A type that looks more like ordinary throat cancer under the microscope; less commonly linked to the Epstein-Barr virus. |
| Non-keratinizing carcinoma | The most common type worldwide, strongly associated with the Epstein-Barr virus and especially sensitive to radiation. |
| Undifferentiated carcinoma | A subtype of non-keratinizing cancer with primitive-looking cells; responds well to radiation and chemotherapy. |
| EBV-associated disease | Most nasopharyngeal cancers carry the Epstein-Barr virus, and blood tests for the virus can help guide diagnosis and follow-up. |
Staging, in plain terms
Nasopharyngeal cancer is staged using the TNM system: how far the Tumor has spread within the nasopharynx and toward the skull base, whether nearby lymph Nodes in the neck are involved, and whether it has spread (Metastasized) to distant organs. Because the cancer is usually linked to the Epstein-Barr virus, doctors can also measure the virus's DNA in the blood, which helps gauge how much cancer is present and track the response to treatment.
| TNM (with EBV DNA levels) | What it generally means |
|---|---|
| Stage 1 | A cancer confined to the nasopharynx, without lymph node or distant spread — usually treated with radiation alone. |
| Stage 2 | The cancer has spread to nearby tissue or to lymph nodes on one side of the neck; radiation is often combined with chemotherapy. |
| Stage 3 | More extensive local growth or lymph node spread on both sides of the neck; treated with combined radiation and chemotherapy. |
| Stage 4 | Cancer that has grown into the skull base or nearby structures, involves large lymph nodes, or has spread to distant organs — treated with chemotherapy and radiation, sometimes in sequence. |
The standard of care
Nasopharyngeal Cancer is almost always treated by a team that may include a surgeon, a medical oncologist, and a radiation oncologist, combining therapies for the best result. The usual building blocks are:
Radiation therapy
Radiation is the backbone of treatment. Because the nasopharynx is hard to reach surgically and the cancer is very radiation-sensitive, precisely targeted radiation (IMRT) treats the tumor and at-risk lymph nodes, and is often curative.
Chemotherapy with radiation
For all but the earliest cancers, chemotherapy is given alongside radiation to make it more effective, and often before or after as well, improving the chance of cure.
Immunotherapy
For advanced or recurrent disease, medicines that help the immune system recognize the cancer are increasingly used, often together with chemotherapy.
Surgery (limited role)
Surgery is generally reserved for removing lymph nodes that persist after treatment or, rarely, for cancer that comes back in the nasopharynx, rather than as the first treatment.
How radiation treatment works
Radiation uses focused high-energy x-rays to damage the DNA inside tumor cells so they can no longer grow and divide. Nasopharyngeal cancer is unusually sensitive to radiation, which is fortunate because the tumor sits deep behind the nose where surgery is very difficult. Modern intensity-modulated radiation therapy (IMRT) shapes the dose precisely around the tumor and the lymph nodes in the neck while protecting the brain, spinal cord, eyes, ears, and salivary glands nearby. Radiation is usually combined with chemotherapy, which makes the cancer cells even more vulnerable. Treatments are painless and brief, given over a series of short daily sessions across several weeks. Side effects depend on the area treated and may include temporary dry mouth, taste changes, sore throat, or skin irritation, many of which improve over time. For nasopharyngeal cancer, radiation is not a supporting tool — it is the main, often curative treatment.
The main ways radiation is delivered for nasopharyngeal cancer:
Intensity-modulated radiation (IMRT)
Computer-shaped radiation beams wrap the dose tightly around the tumor and at-risk lymph nodes while sparing the brain, spinal cord, eyes, and salivary glands — the standard way to treat this cancer.
Chemoradiation
Radiation given together with chemotherapy works better than radiation alone for most stages, because the chemotherapy makes cancer cells more vulnerable to the radiation.
Re-irradiation / stereotactic boost
For cancer that returns in the nasopharynx, highly focused radiation can sometimes deliver an additional precise dose to control the disease while limiting harm to nearby tissue.
Latest studies shaping care
Care keeps improving — often toward getting the same excellent results with less burden on patients. A few developments:
Adding chemotherapy improves cure rates: Combining chemotherapy with radiation — and giving additional chemotherapy before treatment — has been shown to improve survival for locally advanced nasopharyngeal cancer compared with radiation alone.[1]
Induction chemotherapy trials, New England Journal of Medicine
Blood tests for Epstein-Barr virus guide care: Measuring Epstein-Barr virus DNA in the blood helps doctors estimate how much cancer is present, monitor the response to treatment, and detect recurrence early.[2]
EBV DNA biomarker studies, Journal of Clinical Oncology
Immunotherapy for advanced disease: Adding immune-checkpoint medicines to chemotherapy has improved outcomes for recurrent or spread nasopharyngeal cancer, offering new options beyond chemotherapy alone.[3]

Common questions
Why isn't nasopharyngeal cancer treated with surgery? The nasopharynx sits deep behind the nose, near the base of the skull and important nerves and blood vessels, making surgery very difficult. Fortunately, this cancer is highly sensitive to radiation, so radiation — usually with chemotherapy — is the main and often curative treatment instead.
What does the Epstein-Barr virus have to do with it? Most nasopharyngeal cancers carry the Epstein-Barr virus, a common virus that also causes mononucleosis. Having the virus is very common and does not mean you'll get this cancer, but in these tumors doctors can measure the virus's DNA in the blood to help guide diagnosis and follow-up.
Can nasopharyngeal cancer be cured? Yes. Because it responds so well to radiation, many patients — especially those whose cancer is found before it spreads to distant organs — are cured. Combining radiation with chemotherapy further improves the chance of cure for more advanced disease.
