How long a patient with pancreatic head cancer can live after successful early surgery cannot be generalized and is related to the patient’s physical condition and state of mind. The anatomical structure of the pancreas includes the head, body and tail of the pancreas, while pancreatic head cancer is a malignant tumor originating from the pancreatic head area. If detected early, patients are recommended to undergo surgery in time. Surgical resection is the only possible way to cure pancreatic head cancer. If early surgery is successful, due to the high malignancy of pancreatic head cancer, the 5-year survival rate after surgery may not exceed 15%, and the median survival period (i.e. the time when 50% and only 50% of individuals can survive) is only about 12 months. However, the above are only statistical data, and there are individual differences in the specific survival of patients. Patients are advised to actively cooperate with the treatment and adjust their mentality, which is conducive to prolonging the survival period. In addition, patients should also pay attention to a low-fat diet after surgery, and appropriately supplement high-quality protein, vitamins and other nutritional elements to improve the body’s resistance.
