The causes of pancreatic cancer are not yet entirely clear, but its occurrence is associated with smoking, drinking alcohol, high-fat and high-protein diets, excessive consumption of coffee, environmental pollution, and genetic factors. Recent surveys have found that the incidence of pancreatic cancer is significantly higher among diabetics than in the general population. There is also evidence suggesting a certain relationship between chronic pancreatitis and the development of pancreatic cancer, with a notably increased risk of pancreatic cancer among patients with chronic pancreatitis. Additionally, many other factors such as occupation, environment, and geography are somewhat related to the occurrence of this disease. Pancreatic cancer is not a cancer that comes from anger or emotional causes.
