What is nasopharynx (nose) cancer?

Nasopharynx or nasopharyngeal cancer, commonly known as nose cancer, is an abnormal growth of tissue in the nasopharynx, the area behind the nose just above the mouth and throat.

This abnormal growth is called a tumour that develops when the cells in the nasopharynx divide uncontrollably and produce extra tissue.

Nasopharynx cancer can be benign (non-cancerous) or malignant (cancerous). In Singapore, it is the 6th most common head and neck cancer in men.

What are the risk factors for nasopharynx (nose) cancer?

There are several risk factors that can increase the chances of developing nose cancer:

Tobacco smoking
An Epstein-Barr virus (EBV) infection – This usually results in mild symptoms such as fever and sore throat. It has been linked to nose cancer as the virus has been found in nearly all nose cancer cells. However, an EBV infection on its own is not enough to cause nose cancer.
Ethnicity and gender – Chinese (especially Cantonese) and men aged 20 – 50 years are more likely to develop nose cancer.
Certain dietary habits – Nose cancer is common in Asia, North Africa and the Arctic, where people are known for consuming diets high in salt, cured fish and meat.
