As the saying goes, "disease enters through the mouth," will cancer also be "eaten out"? April 15th to 21st this year is the 30th National Cancer Prevention and Control Awareness Week. Experts remind that among many carcinogenic factors, some are closely related to diet, especially for digestive system tumors such as esophageal cancer, gastric cancer, and colon cancer. It is important to be careful not to let the disease enter through the mouth. In China, the high incidence of esophageal cancer is related to some dietary habits. "Eating hot food for a long time will increase the risk of esophageal cancer." Chen Keneng, director of the First Department of Thoracic Surgery of Peking University Cancer Hospital, said that some regions like to drink "Kung Fu tea" just brewed, hot pot, Spicy Hot Pot, Congee and other foods "eat while hot". Eating foods with high temperature for a long time can cause chronic inflammation of the esophageal mucosa, increasing the risk of cancer. It is recommended that the imported food be safe below 50 degrees Celsius. Chen Keneng suggests that the onset of esophageal cancer is insidious, and early symptoms are not obvious. Many patients experience symptoms in the local advanced stage. The incidence rate of benign esophageal diseases is low. If you feel that swallowing is not smooth or even difficult, you should pay special attention to it and seek medical advice in time to check the possibility of esophageal cancer. People with a family history of esophageal cancer, living in areas with high incidence of esophageal cancer, smoking and drinking, and unhealthy dietary habits should be particularly vigilant. China is also a country with a high incidence of gastric cancer. Shaanxi Fei, Deputy Director of the Gastrointestinal Oncology Center of Peking University Cancer Hospital, introduced that Helicobacter pylori infection is the main pathogenic factor for chronic gastritis, peptic ulcers, and gastric cancer. The transmission routes of Helicobacter pylori mainly include oral and fecal oral transmission, and sharing utensils can significantly increase the risk of infection. It is recommended to pay attention to screening for Helicobacter pylori infection during physical examinations. Infected individuals should follow medical advice and take medication in a standardized manner. In daily life, it is advisable to divide meals or use public chopsticks and spoons. In addition, high salt and pickled foods can significantly increase the risk of developing stomach cancer. "In recent years, the incidence rate of colorectal cancer in China has increased, which has a certain relationship with the change of eating habits." Shaanxi Flying suggested that the long-term diet structure is unreasonable, such as large fish and meat, excessive consumption of high-fat and high protein foods, dislike of fresh vegetables, and lack of dietary fiber in food are all high-risk factors for colorectal cancer. If blood in the stool is found in daily life, do not assume it is hemorrhoids. You should seek medical attention in a timely manner and use methods such as colonoscopy to investigate the possibility of colorectal cancer.
