Nasopharyngeal cancer, also known as nasopharyngeal carcinoma (NPC), is a rare type of head and neck cancer that starts in the upper part of the throat, behind the nose. This area is called the nasopharynx and is located at the base of the skull, above the roof of the mouth.
The exact cause of nasopharyngeal cancer is not known, but scientists have found a strong link between this type of cancer and the Epstein-Barr virus (EBV). However, not everyone who has had an EBV infection will develop nasopharyngeal cancer. Other factors that may increase the risk of developing NPC include:
Eating a diet rich in salt-cured fish and meat
Tobacco and alcohol use
Exposure to wood dust or formaldehyde
Family history of nasopharyngeal cancer
Certain genetic factors
The most common symptom of nasopharyngeal cancer is a lump in the neck. Other symptoms may include:
Blurry or double vision
Recurring ear infections
Face pain or numbness
Headache
Hearing loss, ringing in the ears, or a feeling of fullness in the ear
Difficulty opening the mouth
Nosebleeds
Stuffy nose
Sore throat
It is important to note that these symptoms can also be caused by other, less serious conditions. If you experience any of these symptoms, it is best to consult with a doctor for a proper diagnosis.
To diagnose nasopharyngeal cancer, your doctor will start by asking about your symptoms, medical history, and family history, followed by a physical exam. This may include a detailed examination of your ears, nose, and throat by an otolaryngologist (a doctor who specializes in these areas).
If the exam is abnormal, your doctor may recommend a biopsy, which involves removing a small amount of tissue for examination under a microscope. Imaging tests such as chest X-rays, CT scans, MRIs, and ultrasounds may also be used to help spot nasopharyngeal cancer or determine if it has spread.
Treatment for nasopharyngeal cancer depends on several factors, including the location and stage of the tumor, as well as the patient's overall health. The main treatment options include:
Radiation therapy: This is usually part of the standard treatment for early-stage nasopharyngeal cancer. It uses X-rays to kill cancer cells and stop them from growing.
Chemotherapy: While not usually helpful on its own, chemotherapy may help patients live longer when combined with radiation therapy or biological drugs.
Surgery: Surgery to remove the tumor is not often performed due to the tumor's location near nerves and blood vessels, which can lead to permanent damage.
Biologic drugs: These drugs affect how the body's immune system fights disease and may be used more often in cases of advanced or recurrent cancer.
Palliative therapy: The goal of palliative treatment is to control symptoms related to cancer and cancer treatment and make the patient as comfortable as possible.
Clinical trials: If standard treatments are not effective, patients may consider joining a clinical trial to access new and experimental treatment options.
