genetic epidemiological study shows that 12.3% of nasopharyngeal carcinoma patients have a family history. In addition to genetic factors, eating habits are also closely related to nasopharyngeal carcinoma. Eating habits vary from place to place. Therefore, some areas have higher chances of nasopharyngeal cancer, and these areas are the regional preferences for nasopharyngeal cancer.
This issue of "Health Medicine Classroom" has invited Professor Hua Yijun, PhD, and associate chief physician of the Tumor Prevention and Treatment Center of Sun Yat-sen University. He will give a detailed explanation on the topic of "How to prevent high-risk groups in nasopharyngeal cancer".
Naropharyngeal carcinoma occurs frequently in local areas such as South China, Southeast Asia, Mediterranean and Greenland Island. Among them, Guangdong's Zhongshan , Sihui , and Guangxi's Wuzhou , ranks first in the world in the incidence rate.
out of 100,000 people per year, about 20-40 people are diagnosed with nasopharyngeal cancer, about 20 times that of other low-incidence areas.
Therefore, nasopharyngeal carcinoma is also called " Guangdong Cancer ".
How to prevent nasopharyngeal cancer in high-risk groups?
According to WHO 2018 data, the number of new cases and deaths of nasopharyngeal cancer in my country accounted for 46.9% and 43% of the world respectively. Nasopharyngeal carcinoma is a major health problem in Guangdong, especially in the Pearl River Delta and the Xijiang River Basin. It is recommended that people in Guangdong learn more about nasopharyngeal cancer and pay attention to the prevention of nasopharyngeal cancer!

followed by eating more fresh vegetables and fruits, supplements with various vitamins, and should be actively treated for nasopharyngeal epithelial hyperplasia.
3, high-risk populations from high-risk areas should be screened regularly. recommends serological examination of EB virus, such as VCA-IgA, EA-IgA and EB virus DNA copy number. If the numerical value increases abnormally, it is necessary to combine endoscopy or even magnetic resonance inspection if necessary. If there is any suspicion, biopsy should be performed in time.
Finally, tinnitus , headache, lymph node swollen, nausea, diplopia, etc., should be taken seriously and seek medical treatment and checked in time.
