In general, patients with inoperable pancreatic cancer have a survival period of about 3-6 months, those treated with palliative bypass surgery have a survival period of about 7-12 months, and those who undergo radical pancreatic cancer surgery generally survive for 15-24 months. Pancreatic cancer is a highly malignant tumor of the digestive tract, with late detection, rapid progression, difficult treatment and poor prognosis, and most patients have metastases by the time of diagnosis. The survival period of pancreatic cancer patients is generally short. The specific life expectancy of each patient may vary depending on their clinical stage at diagnosis, size of the mass, treatment plan and their own factors, such as age, physical condition, mentality, underlying diseases and socioeconomic conditions. The earlier pancreatic cancer is detected, the greater the possibility of radical resection and the 2-year survival rate of patients with postoperative adjuvant radiotherapy can reach 40%. However, due to the insidious location of pancreatic cancer and atypical early symptoms, most patients are seen for secondary cholangitis, obstructive jaundice, etc. They may have already entered the middle and late stages of the disease, so the possibility of radical resection is very small, and most of them can relieve pain through palliative surgery or control the disease with radiotherapy. In life, pancreatic cancer patients should pay attention to a light diet, choose to eat highly nutritious, easily digestible and low-fat foods, and avoid overeating and alcohol abuse. At the same time, maintaining a good state of mind will have a positive effect on controlling the disease.
