Gastric tumors are common diseases of the digestive system caused by occupational lesions in the stomach, and can be divided into two types: benign tumors and malignant tumors. Benign tumors in the stomach mainly include gastric neurofibroma, gastric mesenchymal tumor, gastric lipoma, etc. Benign tumors in the stomach will not pose serious threat to patients’ life safety as long as they receive timely standardized treatment. However, malignant tumors will infiltrate and destroy the normal organs and tissues of patients because of the characteristics of metastasis and spread. Once the treatment is not timely, it will seriously endanger the survival of patients. Moreover, the earlier the pathological stage of malignant tumor in the stomach, the higher the survival rate. At present, for the determination of the nature of gastric tumor, diagnostic assessment can be made by abdominal CT, biopsy and gastroscopy.
