Nasopharyngeal cancer (NPC) develops when the cells of the lining of the nasopharynx become cancerous. A cancerous lump is formed which then spreads from the nasopharynx into the brain, ear and the jaw. It also spreads into lymph glands on both sides of the neck, and via the bloodstream to the bones and lungs.
Where is the Nasopharynx?
The nasopharynx is located behind our nose and below the brain. It connects our nose to our windpipe, and also to each ear via a tube on its sidewall.
Nasopharyngeal Cancer Risk Factors
- Diet. NPC is associated with the consumption of salted and preserved vegetables, fish and meat.
A recent study in Singapore identified salted soy beans, canned pickled vegetables, Szechuan vegetables and salted vegetables as high-risk foods. The cooking of such foods releases toxins called nitrosamines into the fumes that we breathe. - Epstein Barr Virus (EB Virus). This virus has been found to be associated with NPC.
- Genetics. Genetic factors may play a role in NPC. It is more common in Chinese (especially Cantonese) males aged 35-55 years old.
