There is no specific number of years from the appearance of painful symptoms to death of pancreatic cancer patients, but it is usually not long. It needs to be analyzed according to the stage of the tumor, the patient’s physical condition, treatment methods and other factors. Pancreatic cancer is a malignant tumor mainly originated from pancreatic ductal epithelium and alveolar cells, with high malignancy and insidious onset. Early stage pancreatic cancer is usually treated by surgery and postoperative radiotherapy, the prognosis is usually still good. In the middle and late stages of pancreatic cancer, distant metastasis occurs and the prognosis is very poor, with a 5-year survival rate of about 5%. If you choose conservative treatment, the survival time of advanced pancreatic cancer patients may only be about 3 months. Patients with pancreatic cancer should be treated as soon as possible for painful symptoms, and if necessary, pain management should be provided to reduce pain and improve quality of life.
