Stomach cancer is diagnosed early.

Gastroscopy, upper gastrointestinal imaging, tumor marker detection, pathological biopsy and other examinations can be done in the early stage of gastric cancer. 1. Gastroscopy This is one of the most important means of diagnosing gastric cancer. By inserting the fiber hose with camera into the stomach, the gastric mucosa can be directly observed, and the lesion site, size, shape, etc. can be clearly discovered. For suspicious lesions, biopsy can also be performed to confirm pathological diagnosis. 2. Upper gastrointestinal imaging can show the shape and outline of the stomach, but the diagnostic accuracy for early gastric cancer is relatively low, and it can be used as an auxiliary examination method. 3. Detection of tumor markers such as carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199), etc. Although its elevation does not necessarily mean gastric cancer, it has certain reference value in the diagnosis and monitoring of gastric cancer. 4. Pathological biopsy This is the gold standard for the diagnosis of gastric cancer. After suspicious lesions are found in gastroscopy, biopsy specimens are obtained for pathological analysis, which can accurately determine whether gastric cancer and its type. For the early diagnosis of gastric cancer, it is necessary to comprehensively use a variety of examination methods in order to detect the lesions as soon as possible and treat them in time to improve the survival rate and quality of life of patients. At the same time, for high-risk groups such as family history of gastric cancer, long-term bad eating habits and Helicobacter pylori infection, more attention should be paid to regular examination.
