Early stage gastric cancer generally refers to gastric cancer infiltration depth is very shallow, which may invade the mucosal layer or submucosal layer, and there may be lymph node metastasis or no lymph node metastasis, which is called early stage gastric cancer. When early gastric cancer is examined by gastroscopy, generally depressed lesions or elevated lesions can be found in the stomach, and the lesions are relatively small and the tissues around the lesions are basically normal, or they may have ulcerative changes. Early stage gastric cancer requires surgery, which usually requires removal of the stomach tumor and removal of the lymph nodes in the area. After surgery, chemotherapy is usually not required for regular follow-up, and the 5-year survival rate is generally very high.
