According to Xinhua News Agency, the reporter learned from the International Symposium on Gastrointestinal Tumors held here that the incidence of colorectal cancer, colon cancer, liver cancer and pancreatic cancer and other malignant tumors of the digestive system in China has been on the rise in recent years, and there is a tendency of rejuvenation. Experts pointed out that poor dietary habits, poor lifestyle and unbalanced nutritional intake are important reasons for the occurrence of digestive system cancers. In recent years, the incidence of digestive system tumors has changed due to the change of dietary habits. The latest tumor epidemiological data show that the incidence of gastric cancer and esophageal cancer is decreasing, while colorectal cancer and pancreatic cancer are still on the rise. Hao Xishan, academician of Chinese Academy of Engineering and president of Tianjin Medical University Cancer Hospital, said that the high incidence of pancreatic cancer and colorectal cancer is directly related to the westernization of people’s life, excessive intake of high-fat diet and insufficient intake of food fiber, and the reduction of sports. Especially, pancreatic cancer has become the new king of cancer because of its rapid growth, insidious onset, rapid progress and high mortality rate. It is understood that in major cities such as Beijing and Shanghai in China, the incidence of pancreatic cancer has increased four times in the past 20 years, making it the region with the highest incidence of pancreatic cancer in China. Among the top 5 tumors in terms of incidence growth in Tianjin, pancreatic cancer in women is growing at the fastest rate, followed by men. Experts say that the early symptoms of pancreatic cancer are not obvious and only 20% of patients have the opportunity to have surgery when they are seen. Experts say that comprehensive treatment, mainly surgery, is the preferred treatment for digestive system tumors. Early detection and early diagnosis are necessary to achieve early treatment. Symptoms such as sudden unexplained weight loss, decreased appetite, change in stool pattern (especially alternating constipation and diarrhea), blood in stool (black stool) or occult blood, and unexplained long-term abdominal pain should be alerted.
