Lymphatic hyperplasia in the stomach is not necessarily cancerous, but we should be alert to the possibility of cancer in the stomach. Lymphatic hyperplasia in the stomach usually suggests inflammation or gastric ulcer in the stomach, which leads to lymphatic tissue hyperplasia. It is a kind of benign hyperplasia, which will not be cancerous directly, but may be accompanied by early gastric cancer, so further examination is needed to exclude it. If lymphatic hyperplasia is found in stomach, gastroscopy or barium meal should be done to exclude gastric cancer, and biopsy can be taken according to lymphatic hyperplasia and gastric ulcer and sent to pathology for early detection and early treatment. Although lymphatic hyperplasia in the stomach is caused by inflammation and will not become cancerous, it is necessary to be alert to the possibility of early gastric cancer.
