Pancreatitis usually does not turn into cancer, but a few patients can develop cancer on the basis of chronic inflammation of the pancreas; some studies also show that chronic pancreatitis is one of the risk factors for pancreatic cancer. Pancreatic cancer is a malignant tumor of the digestive tract with insidious onset, rapid progression, and extremely poor therapeutic effect and prognosis, and its incidence has been on the rise worldwide. The etiology of pancreatic cancer is not yet clear, and its risk factors mainly include long-term smoking, obesity, long-term heavy drinking, chronic pancreatitis, diabetes mellitus, long-term exposure to chemical substances, high-fat and high-protein diets, and heredity. Studies have shown that patients with chronic pancreatitis, especially those with familial pancreatitis, also have an increased risk of developing pancreatic cancer. Pancreatitis includes acute pancreatitis and chronic pancreatitis. Acute pancreatitis is a common acute abdominal disease with a complex pathogenesis, which usually does not turn into cancer. Chronic pancreatitis is irreversible chronic inflammatory damage to the pancreas caused by various reasons, with atrophy and fibrosis of the pancreatic glands in the form of irregular nodular sclerosis, but a small number of people can develop cancer on the basis of chronic inflammation of the pancreas. If pancreatic cancer is suspected or diagnosed, it is recommended to go to a regular hospital for comprehensive assessment of the condition and follow the doctor’s instructions to avoid delaying the condition.
