Nasopharyngeal carcinoma
What is NPC?
Nasopharyngeal carcinoma (NPC) is a cancer that develops in the nasopharynx—the upper part of the throat, behind the nose. It has a strong link to Epstein-Barr virus (EBV) infection, especially in certain parts of the world.
Who is affected?
NPC is rare in most countries (less than 1 case per 100,000 people). However, it is much more common in southern China, Southeast Asia, the Arctic region, and North Africa.
Risk factors
Several factors may increase the risk of developing NPC:
Epstein-Barr virus (EBV): This virus plays a central role in the development of NPC
Diet: consumption of salt-preserved foods, particularly salted fish, has been linked to higher risk.
Genetics: Some people may have an inherited susceptibility
Smoking: Associated with worse outcomes
Signs and symptoms
NPC is often diagnosed at a later stage because early symptoms can be vague and the nasopharynx is difficult to examine.
Common signs include:
A painless lump in the neck (enlarged lymph nodes)
Blocked nose or nosebleeds
Hearing changes, ear fullness, or fluid in the middle ear
In advanced cases, symptoms related to nerve involvement
Impact on daily life
NPC and its treatment can cause effects that may persist over time, including:
- Dry mouth
- Hearing changes
- Difficulty swallowing
- Fatigue
- Hormonal changes
- Cognitive effects
- Emotional challenges
These can affect daily activities, work, and relationships. Speaking with your healthcare team about any concerns is important—support is available.
Diagnosis and staging
How is NPC diagnosed?
A biopsy (tissue sample) is needed to confirm the diagnosis, usually obtained through an endoscopy of the nasopharynx. Imaging scans (CT, MRI, and sometimes PET-CT) help determine how far the cancer has spread.
Staging
Accurate staging (according to the AJCC/UICC 9th edition TNM system) is a fundamental step in treating patients with NPC, as it is crucial for prognostication and for guiding treatment decisions.
Monitoring
In some settings, a blood test measuring EBV DNA can help with monitoring treatment response and detecting recurrence.
Managing NPC
While a new diagnosis can feel overwhelming, there are effective treatments to help manage the disease at different stages. Treatment is determined based on the stage of the cancer. The therapeutic management needs to be established according to the case of each patient. Care is typically coordinated through a specialist multidisciplinary team — healthcare professionals who work together in a tumor board or multidisciplinary clinic to plan the most appropriate approach.
Depending on the clinical situation, treatment options can include radiotherapy, chemotherapy, or a combination of both; in some cases, immunotherapy or targeted therapy may also be considered. The healthcare team works collaboratively to provide comprehensive, patient-centered care.
Follow-up Care
Regular follow-up after treatment helps to:
- Monitor for any signs of recurrence
- Manage lasting effects of treatment
- Support overall well-being
Follow-up usually includes physical exams, endoscopy, and imaging when appropriate. Maintaining healthy habits—especially avoiding tobacco and looking after dental health—supports long-term health.
Care often involves a team of professionals, including oncologists, ENT specialists, dentists, and primary care doctors, working together to provide comprehensive support.
