Who are the high-risk groups for pancreatic cancer?

People at high risk for pancreatic cancer include:

1. People over 40 years old have non-specific upper abdominal symptoms, such as intermittent upper abdominal pain or unexplained persistent upper abdominal and back pain, unexplained anorexia and weight loss, etc.

2. Sudden onset of diabetes, especially atypical diabetes, in patients over 60 years old, with no family history, no obesity, and who quickly develop insulin resistance. 40% of pancreatic cancer patients have diabetes when diagnosed.

3. Recurrent pancreatitis and chronic pancreatitis are important precancerous lesions in a small number of patients, especially chronic familial pancreatitis and chronic calcific pancreatitis.

4. Familial adenomatous polyposis. The incidence of this disease combined with pancreatic cancer is higher than that of the normal population.

5. There is a family history of pancreatic cancer.

6. Smoking, heavy drinking, occupational exposure, long-term high-fat diet and obesity.

7. After subtotal gastrectomy for benign lesions, the incidence of pancreatic cancer increases by 1.65 to 5 times, especially in people more than 20 years after surgery.
