How long pancreatic cancer can generally live under conservative treatment depends on the characteristics and stage of the tumor as well as the patient’s physical quality and psychological state, etc. The effect of treatment varies with different specific conditions, and there are individual differences in survival time. However, most of its early symptoms are not obvious, such as foreign body sensation after eating, post-sternal distention or slight pain, and so on, and they usually appear indirectly, so it is not easy to be detected. In the middle and late stages, the related symptoms will continue to appear or worsen progressively, the conservative treatment effect is relatively poor, the 5-year survival rate is low, and only radiotherapy can be chosen in the late stages, and surgical intervention is not possible. Therefore, once patients appear unwell, they should be admitted to the hospital in time for examination, to achieve early detection, early diagnosis and early treatment, and to maintain a positive and good attitude, which can effectively prolong their survival time.
