The most common and preferred way to check for gastric cancer is gastroscopy and pathological diagnosis. If you are afraid of pain, consider painless gastroscopy or a full abdominal CT, upper gastrointestinal tract imaging, etc. as a means of screening.
The best way to screen for gastric cancer is gastroscopy plus pathological diagnosis. If you are very afraid that gastroscopy will be too painful, there is now a painless gastroscopy option, which has the advantage of determining the location, size, morphology, and pathological staging of gastric cancer in a very direct way.
In addition, there are other tests, such as whole abdomen CT or upper gastrointestinal imaging, such as barium swallow. Gastric cancer is a relatively common tumor disease with no particular symptoms in the early stages, and when symptoms appear it is already in the middle to late stages, so it is very important to have regular gastric cancer screenings.
For healthy adults, you can do a fecal occult blood test, and if it is positive, then consider a gastroscopy. If any abnormalities are found in the gastric mucosa, then take the tissue from the lesion for pathological analysis, which can be used to screen out early gastric cancer. For adults who already have symptoms of stomach discomfort or are over the age of 50, regular stomach examinations can be done.
