This week (April 15-21) is the 30th National Cancer Prevention and Treatment Publicity Week, with the theme of "Comprehensive Policies and Scientific Cancer Prevention". According to the 2022 disease burden of malignant tumors in China released by the National Cancer Center, digestive tract cancer accounts for a prominent proportion, and esophageal cancer is a type of digestive tract malignancy with a high incidence in mainland China, with about half of the world's esophageal cancer patients in China. Data shows that in 2022, there will be 224,000 new cases of esophageal cancer in mainland China.
Esophageal cancer is a malignant tumor that occurs in the esophageal mucosa, mainly including esophageal squamous cell carcinoma and esophageal adenocarcinoma, accounting for more than 90% of esophageal squamous cell carcinoma in mainland China.
Mao Yousheng, Chief Physician of the Department of Thoracic Surgery, Cancer Hospital of the Chinese Academy of Medical Sciences: Generally, there are no obvious symptoms in the early stage of esophageal cancer, and there may be only occasional painful swallowing, or a foreign body sensation, and the symptoms are recurring. However, the symptoms of middle and advanced esophageal cancer are very obvious, there may be swallowing problems, painful swallowing, swallowing obstruction, etc., and even some cachexia changes, unable to eat at all, dripping, swollen lymph nodes, pain in other places and so on.
Mr. Liu, 64 years old this year, went to the hospital at the end of last year due to difficulty eating and swallowing, and was diagnosed with esophageal cancer after a number of examinations such as gastrointestinal endoscopy. After subsequent treatment, Mr. Liu's condition was effectively controlled.
Mr. Liu told reporters that in terms of eating habits, he usually likes to eat hot food, likes to drink hot porridge, and likes to eat pickled food. According to the doctor, these lifestyle habits greatly increased his risk of esophageal cancer.
Wang Zhen, Chief Physician of the Department of Thoracic Surgery, Cancer Hospital, Chinese Academy of Medical Sciences: Esophageal cancer is a disease in which genetics, environment and lifestyle habits interact, and its high incidence factors include lifestyle habits in addition to genetic factors. Some bad habits, such as smoking, drinking, eating hot food, eating fast, liking to eat pickled food, etc.
According to experts, the incidence of esophageal cancer has obvious geographical clustering in the mainland, and the high-incidence areas are mainly concentrated in the Taihang Mountains such as Henan, Hebei and Shanxi, as well as Anhui, northern Jiangsu, Shantou in Guangdong, and southern Fujian in Fujian.
Mao Yousheng, Chief Physician of the Department of Thoracic Surgery, Cancer Hospital, Chinese Academy of Medical Sciences: Selenium and zinc can be supplemented in high-incidence areas, which can delay or reduce the incidence of esophageal cancer. Studies in high-incidence areas have shown that the incidence of esophageal cancer in China is decreasing year by year, which is a very good trend.
