Everyone has a fear of disease, because it means that something is wrong with our body. Let’s learn more about it today. The cause of pancreatic cancer is still unclear. Smoking, alcohol consumption, high fat and animal protein diet, coffee consumption and diabetes may be related to its attack. The ratio of men to women in pancreatic cancer is 1.7-2.0:1, and 40% of patients are over 40 years old. The onset of pancreatic cancer is insidious, and the onset of the disease is mostly late, with low surgical resection rate. Therefore, the early detection and inductive treatment can improve the curative effect of pancreatic cancer and then improve the prognosis. Liu Ning advocates to be alert to the early manifestations of pancreatic cancer so as to facilitate early detection and timely treatment. The pancreas is located in the deep part of the abdominal cavity and is surrounded by many important blood vessels such as the abdominal aorta, inferior vena cava, portal vein, superior mesenteric artery, portal vein and splenic vein. If there is a lack of insulin produced by the pancreas, it will lead to diabetes. Pancreatic cancer is a relatively rare malignant tumor of the digestive tract, and its incidence has been on the rise in recent years. The expansion of pancreatic cancer lesions can easily involve some of the above-mentioned blood vessels and thus cannot be removed. The head of the pancreas is also located in the “traffic hub” of the digestive tract. Pancreatic cancer can cause blockage of the bile duct, pancreatic duct and even duodenum, resulting in obstructive jaundice, dyspepsia and digestive tract obstruction.
