Pancreatic cancer is a malignant tumor of the digestive system, which is generally difficult to treat and may not survive for a long time. Most inoperable pancreatic cancers have an average survival period of about 3-6 months. The day before pancreatic cancer dies, the symptoms that may manifest are mainly severe abdominal distension, abdominal pain, respiratory failure, liver failure, or cause multiple metastases, leading to circulatory failure and gradually leading to death, and most of the causes of pancreatic cancer death are still the failure of vital organs. Pancreatic cancer usually causes severe abdominal pain, mainly around the navel and upper abdomen, which may not be effective with general pain medications. In advanced pancreatic cancer, we should try to relieve the pain and strengthen the companionship, but there is no other good way.
