How much do you know about nasopharyngeal cancer, is it because of salted fish?
Frequent consumption of pickled or smoked food: Nasopharyngeal cancer is more common in Chinese and Eskimos, and the incidence of the disease is much higher than that of European, American, Japanese, and Korean ethnic groups, and the incidence of the disease is higher in the southeastern coastal areas of China and Taiwan than in northern China, especially It is located in Guangdong, so it is also known as "Cantonese Cancer". Even overseas Chinese who have moved overseas have a higher chance of getting sick than locals. In the past, it was generally believed that this was closely related to the consumption of salted fish because salted fish contained carcinogenic nitrosamines. However, this statement cannot explain that immigrants who have migrated overseas and have no habit of eating salted fish and their descendants still have a high morbidity rate, and those who have migrated from other places to Guangdong and have the habit of eating salted fish do not have a high morbidity rate. Therefore, it is now generally believed that genetics is the main pathogenic factor of nasopharyngeal carcinoma.
