The time it takes for pancreatic cancer to progress from early to advanced stages depends on the patient’s immunity, the patient’s general condition as well as the specific type of pathology and location of the pancreatic cancer. Generally speaking, pancreatic cancer is a highly malignant tumor with rapid progression, and most of the patients may take about half a year to one year from early to late stage if they are not given timely treatment. If active and regular treatment is given, it is possible to prolong the survival period more obviously. Especially for patients with early pancreatic cancer, early surgical resection can achieve better surgical results, and it is possible to achieve long-term survival, such as 3-10 years or more. In addition, for pancreatic cancer if the pathological type is undifferentiated cancer, with high degree of malignancy, rapid growth, early metastasis and infiltration, and the surrounding tissues and organs have already appeared the symptoms of advanced pancreatic cancer, it is possible that rapid progression occurs in 1-3 months. Therefore, the specific situation needs to be analyzed specifically. However, most of the pancreatic cancer, once appeared are patients in the middle and late stages, so the prognosis is poor.
