In terms of pancreatic cancer, due to the special anatomical location of the pancreas, early diagnosis is not easy. Most of the pancreatic cancer patients who come to our department think they have “stomach disease” because of pain in the upper and middle abdomen, and early gastroscopy results show “superficial gastritis”. It is only when the symptoms worsen that the patient is considered to undergo abdominal ultrasound, CT and other imaging examinations, at which time the occupying lesion of the pancreas is suddenly discovered, which greatly delays the best treatment time for pancreatic cancer. According to our clinical experience over the years, when jaundice is suddenly detected and progressively worsens, or when abdominal pain and distension like stomach disease and back pain occur, patients should establish a sense of concern and try to rule out the possibility of malignant disease by using tumor markers, abdominal ultrasound, CT, MRI and PET-CT if possible. At the same time, regular rest and diet, staying away from smoking and alcohol, proper exercise, etc. are all the awareness we should develop to prevent cancer.
