Recently, a well-known actor passed away due to esophageal cancer, which has sparked attention to esophageal cancer. Yang Bingjun, chief physician of the Department of Thoracic Surgery at Tianjin People's Hospital, pointed out that the incidence of esophageal cancer is closely related to poor dietary habits. Stay away from esophageal cancer and maintain good lifestyle and dietary habits. Yang Bingjun introduced that esophageal cancer is a malignant tumor originating from the epithelium of the esophageal mucosa. Typical clinical manifestations include progressive dysphagia, choking sensation, foreign body sensation, burning sensation, stagnation sensation or fullness sensation after eating, with or without pain, acid reflux, heartburn, belching behind the sternum. Initially, it is difficult to enter a regular diet, but gradually deteriorates to only enter a semi liquid or liquid diet. It may or may not be accompanied by chyme or mucus reflux, cough, pus, fever, chest tightness, wheezing, vomiting, hematemesis, etc Black stool, chest and back pain, hoarseness or coughing due to drinking water. Due to difficulty in eating, there is an increased risk of insufficient nutrition intake, which may lead to weight loss, fatigue, fatigue, and weakened physical strength after accumulating for several months. At present, it is known that the incidence of esophageal cancer is closely related to poor dietary habits, including hot eating, hot tea, alcohol consumption, smoking, etc. In addition, it also includes factors such as food mold, charcoal grilling or smoking preparation methods, drinking water, soil composition, or environmental microbial communities. Yang Bingjun reminds us that in daily life, we should try to avoid the triggering factors mentioned above, avoid eating foods that are too hot, spicy, moldy, or high in nitrite content, quit smoking and limit alcohol consumption, eat more fresh vegetables and fruits, and increase dietary fiber intake. Properly control meat intake, increase the intake of high-quality proteins such as fish and legumes, and avoid overnutrition or malnutrition. Pay attention to drinking water hygiene in high-risk areas. Due to the lack of typical clinical symptoms in early esophageal cancer, when patients seek medical attention due to progressive dysphagia or metastatic symptoms, they often belong to the middle to late stage. In fact, before the occurrence of mid to late stage cancer, there is a precancerous state, precancerous lesions, and early cancer stage that can last for 5 to 10 years, providing an important window period for esophageal cancer screening. Therefore, screening and early diagnosis and treatment of high-risk populations for esophageal cancer are important ways to prevent and treat esophageal cancer. The high-risk population for esophageal cancer screening is those aged 40 and above, who meet any of the following criteria: those born or long-term residents in areas with high incidence of esophageal cancer; Suffering from precancerous diseases or precancerous lesions of the upper gastrointestinal tract; First degree relatives have a history of esophageal cancer; Suffering from squamous cell carcinoma of the head, neck, and/or respiratory tract; Having high-risk factors for esophageal cancer (such as heavy smoking, heavy drinking, eating too fast, hot eating habits, indoor air pollution, and missing teeth). High risk populations should undergo regular endoscopic examinations to identify early symptoms and achieve early detection and treatment. Reporter: Liu Bo (Xinhua News Agency)
