The length of life after pancreatic cancer surgery cannot be generalized, but is closely related to the cleanliness of the surgically removed cancerous lesions and the patient’s basic health condition, which requires specific analysis. Generally speaking, pancreatic cancer is very malignant, difficult to treat, and usually has a poor prognosis. However, if the patient can be diagnosed in the early stage of pancreatic cancer and treated surgically, and the cancer can be removed completely, the patient’s prognosis can be improved and the survival period can be prolonged, and some patients can even be cured and survive for a long time. However, if the cancer is not removed cleanly, patients are prone to recurrence and metastasis, which will greatly affect their survival. Patients with pancreatic cancer need to enhance nutrition, control infection, pay attention to rest, increase the intake of fresh fruits and vegetables, avoid drinking alcohol, avoid high-fat and high-protein foods, and follow up and observe regularly and strictly according to medical prescriptions in order to detect signs of recurrence or metastasis and treat them in time.
