Pancreatic cancer is a malignant tumor that occurs in the digestive system clinically. Due to the hidden location of the pancreas, early symptoms of pancreatic cancer are generally not obvious. When individuals with a family history of pancreatic cancer exhibit unexplained fatigue or abdominal discomfort, or rapidly progressive jaundice symptoms in a short period, and if patients also have diseases such as diabetes, the possibility of pancreatic cancer should be considered. An abdominal CT scan, MRI, and other radiological examinations should be completed quickly. For identified pancreatic space-occupying lesions, early biopsy through puncture or direct exploratory laparotomy should be performed as soon as possible for treatment.
