The time from the onset of pancreatic cancer to death is related to the severity of the patient’s condition, general health condition, whether the patient is actively treated and other factors, and cannot be generalized. There is a certain correlation between the onset of pancreatic cancer and dietary habits. Long-term high salt diet, low-fiber and high-fat diet, moldy food, smoking, etc. may increase the incidence of pancreatic cancer. Early stage pancreatic cancer patients are recommended to actively cooperate with surgical treatment, and the 5-year survival rate after surgery can reach about 60%, and some patients can be cured. If the disease is advanced and spreads all over the body, the survival period will be significantly shortened, and most of the patients will die within one year. Therefore, if you want to prevent the occurrence or development of pancreatic cancer, you must develop good living habits, and it is recommended to have a low-salt and low-fat diet, avoid eating moldy food, do not smoke, and eat less fried food.
