Can nasopharyngeal cancer be prevented?
The nasopharynx connects the back of your nose to the back of your throat. It allows you to breathe through your nose and swallow mucus produced by the lining of your nose.
This type of cancer is more common in some ethnic groups, for example people of Chinese origin. In 2014, 834 cases of nasopharyngeal cancer were diagnosed in Hong Kong, making it the tenth most common cancer.
Evidence shows that eating Cantonese-style salted fish can cause this type of cancer.
This means that people eating a south-east Asian diet may be at higher risk of nasopharyngeal cancer.
Smoking also increases the risk of nasopharyngeal cancer. If you do smoke, stopping smoking will reduce your risk.
