Pancreatic nodules are very common in clinical practice and are benign lesions, the most common cause of which is an inflammatory reaction with scarring left over from long-term chronic irritation. There are no obvious clinical symptoms, and they are mostly found during physical examinations. Many patients are very worried after the discovery of pancreatic nodules, adding a lot of unnecessary stress. If there are no obvious clinical symptoms, there is no need to worry and regular checkups are necessary. Some pancreatic nodules and pancreatic cancer are not completely distinguishable from each other in terms of imaging. If you suspect that they are related to pancreatic cancer, you can have further examinations, such as CT or enhanced CT. Pancreatic cancer usually has obvious clinical symptoms, such as pain and eating disorders.
