At our National Cancer Information Center trained Cancer Information Specialists can answer questions 24 hours a day, every day of the year to empower you with accurate, up-to-date information to help you make educated health decisions. We connect patients, caregivers, and family members with valuable services and resources.
Or ask us how you can get involved and support the fight against cancer. Some of the topics we can assist with include:
For medical questions, we encourage you to review our information with your doctor.
Nasopharyngeal cancer is a type of head and neck cancer. Head and neck cancers can have many different names depending on where the cancer starts. Cancer starts when cells in the body begin to grow out of control.
Nasopharyngeal cancer starts in the nasopharynx, the upper part of the throat behind the nose and near the base of skull.
Since the head and neck area has so many organs in a small place, knowing what type of head and neck cancer you have can be confusing. Ask your doctor to write down the exact kind of cancer you have and show you where it is on a picture. To learn more about how cancers start and spread, see What Is Cancer?
The nasopharynx is the upper part of the throat (pharynx) that lies behind the nose and nasal cavity. It's a box-like chamber about 3/4 inches (2 cm) wide and 1½ inches (4 cm) long. It lies just behind the nasal cavity and above the soft part of the roof of the mouth (soft palate). It is located in the upper part of the pharynx. The oropharynx is just below the nasopharynx and the hypopharynx is just below the oropharynx.
The nasopharynx serves as a passageway for air traveling from the nose to the throat.

Several types of tumors can develop in the nasopharynx. Some of these tumors are benign (not cancer), and others are malignant (cancer). It's important to talk with your doctor about what type of tumor you might have.
The most common cancer in the nasopharynx is nasopharyngeal carcinoma (NPC). Carcinoma is cancer that starts in the cells that line the surfaces of organs in the body, called epithelial cells.
There are different types of NPC. They all start from epithelial cells that line the nasopharynx, but the cells of each type look different when looked at closely in the lab:
The treatment is the same for all types of NPC, but the stage of the cancer (how far it has grown and spread) is often more important than the type in predicting a person's outlook (prognosis). Research is being done to evaluate using EBV DNA levels to also help predict a person’s outlook (prognosis), when the NPC is linked to EBV.
Other types of cancers can also be found in the nasopharynx:
Benign nasopharyngeal tumors are fairly rare and tend to develop in children and young adults. These tumors do not spread to other parts of the body and are usually not life-threatening. They include tumors or malformations of the vascular (blood-carrying) system, such as angiofibromas and hemangiomas, and benign tumors of minor salivary glands within the nasopharynx.
Benign nasopharyngeal tumors don't always need treatment. When they do, the treatment is not the same as for nasopharyngeal cancer. If you have a benign tumor, ask your doctor what to expect.
