Cardia polyp is a benign tumor, but it has some cancer potential. There is a large individualized difference in exactly how often it becomes cancerous. Some patients may not become cancerous, and some may become cancerous several months after discovery. Cardia polyps are related to alcohol consumption, irregular diet, inflammatory irritation, genetics and other factors. In the early stage, patients have no obvious symptoms or no symptoms, and they are mostly found during physical examination, at which time they are surgically removed and most of them will not become cancerous. As polyps grow up, patients may experience symptoms such as eating obstruction, choking, increased sputum and mucus, pain, etc. In moderate or severe hyperplasia, cancer may occur, which may take months or years. Therefore, after polyps are found, patients are generally advised to undergo gastroscopic resection and pathological examination as soon as possible to avoid cancerous changes. In addition, patients with gastric polyps are advised to pay attention to less alcohol consumption, regular diet, less spicy and stimulating food, and early surgical removal or regular gastroscopic examination.
