The difference between benign and malignant gastric polyps lies in the difference of whether they are cancerous or not. Gastric polyps themselves are benign tumors, but they are very likely to evolve into gastric cancer, and they are malignant tumors when the polyps become cancerous. When gastric polyps or gastric polyps become cancerous, there is no obvious difference in clinical symptoms in the early stage, that is to say, patients may not have obvious clinical symptoms or show bloating, acid reflux, belching, loss of appetite, etc. In the late stage of gastric cancer, patients may show bloating, acid reflux, belching, loss of appetite and so on. In the late stage of gastric cancer, it will manifest as irregular abdominal pain, accompanied by abdominal distension, black stools, emaciation, poor appetite, etc. For patients with gastric polyps, it is suggested that they need to cooperate with doctors to perform electrocoagulation electrodessication in time in the early stage. If it is adenomatous polyp, it belongs to the precancerous lesion of gastric cancer, which is likely to develop into gastric cancer, and patients need to pay attention to it.
