What tests should be done to diagnose pancreatic cancer?

Generally, people in their forties and fifties will go through a turning point. During this period, if you don't take care of your health, many diseases may appear. In fact, pancreatic cancer is an extremely serious cancer, so people should know something about the diagnosis of pancreatic cancer and have a physical examination in time when necessary. Next, experts will introduce you. 1, CT examination. CT is a very intuitive examination method, which is of great significance to the diagnosis of pancreatic cancer. It can be seen that the pancreas is locally enlarged, deformed or dilated, and the CT density of tumor tissue is different from that of surrounding pancreatic tissue. In patients with pancreatic head cancer, there is a circular or elliptical low-density enlarged bile duct image in the pancreatic head tissue, which shows "ring shadow" sign. CT examination of oral and intravenous contrast media is a good method to evaluate pancreatic tumors. Modern technology can provide more detailed information and reconstruct three-dimensional images through dynamic scanning during rapid injection of intravenous contrast media. 2. Histocytopathological examination. This kind of examination includes a variety of examination methods, which are generally less used in clinic. It mainly includes collecting pancreatic juice through pancreatic duct intubation of duodenoscope for cytological analysis, and using fine needle to puncture the pancreas to absorb cancer cells under the guidance of ct or B-ultrasound. The positive rate was 80%. Recently, it has been reported that a definite diagnosis can be made by taking pancreatic tissue or nearby lymph nodes through laparoscopy, and the positive rate is very high. But they all need certain facilities and technology. When the diagnosis of pancreatic cancer is suspected, B-ultrasound should be performed first, ERCP or CT or even laparotomy should be performed when suspicious points are found, and fine needle aspiration cytology can be performed when conditions permit. 3. Detection of specific tumor antigen. The peripheral blood of the patient was cultured to diagnose the number of cancer cells, tumor load and degree of immune deficiency in the patient. It is the most advanced diagnostic method at present. ? The above introduces the common sense of diagnosis of pancreatic cancer, from which we can see that it is not difficult to diagnose pancreatic cancer now, mainly because patients often have no awareness of active diagnosis, which is determined by people's economic situation and health awareness. The improvement of this situation needs a better opportunity and people's vigorous publicity.
