The resection rate for pancreatic cancer is relatively low because the pancreas is located behind the peritoneum in a deep position. In the early stages of pancreatic cancer, there are often no specific clinical symptoms. Therefore, by the time pancreatic cancer is detected in patients, it is usually already in the advanced stages. The pancreas is surrounded by blood vessels and nerves. Therefore, if it is found in the late stage, the surgical difficulty is very high, making it difficult to remove surgically, which is why the surgical resection rate for pancreatic cancer is low.
