The misdiagnosis rate for pancreatic cancer is relatively high, mainly due to factors such as inconspicuous early symptoms, symptoms resembling other diseases, and limitations in diagnostic methods. In clinical practice, diagnosing pancreatic cancer does present certain challenges.

1. Inconspicuous Early Symptoms: The pancreas is located deep in the abdominal cavity, and early-stage tumors are small, making them unlikely to cause noticeable discomfort. Symptoms such as abdominal pain or indigestion typically appear only when the tumor grows large enough to compress surrounding organs or invade nerves.

2. Symptoms Resemble Other Diseases: The symptoms of pancreatic cancer, such as abdominal pain, bloating, and indigestion, closely resemble those of other digestive system disorders like gastroenteritis, gastric ulcers, and cholecystitis, making misdiagnosis likely.

3. Limitations of Diagnostic Methods: Although imaging techniques such as ultrasound, CT, and MRI can be used to detect pancreatic tumors, these methods have a relatively low detection rate for early-stage pancreatic cancer, which may lead to misdiagnosis. Confirming pancreatic cancer typically requires pathological examination, but due to the pancreas's deep location, biopsy procedures are sometimes limited.

Therefore, when diagnosing pancreatic cancer, doctors need to comprehensively consider clinical manifestations, imaging studies, laboratory tests, and other relevant information to improve diagnostic accuracy. If patients experience discomfort, they should promptly consult a professional doctor and undergo necessary examinations.
