Early stage gastric cancer can choose endoscopic treatment such as endoscopic mucosal resection or surgical treatment such as partial gastrectomy. Early gastric cancer without lymph node metastasis and distant metastasis can choose endoscopic mucosal resection or endoscopic mucosal dissection, and its indications include ultrasonographically endoscopically confirmed intramucosal gastric cancer without lymph node metastasis, without ulceration and <2cm of IIa lesion, <1cm of IIb or IIc lesion, and so on. When the resected cancerous tissue is awakened for pathological examination, if the cancerous lesion at the margin of incision or superficial type of cancer is found to invade into the submucosa, additional surgical treatment needs to be considered. For early gastric cancer, partial gastrectomy is usually chosen. If suffering from gastric cancer, it is recommended to have treatment under the guidance of professional doctors in regular hospitals to avoid delaying the condition.
