Most gastric polyps are not serious. Gastric polyps are usually caused by prolonged inflammation of the gastric mucosa, resulting in abnormal growth. The stomach wall is composed of four layers of tissue: the mucous layer, the submucous layer, the muscular layer, and the plasma layer. When the mucous layer becomes elevated, it is known as a gastric polyp, which is not tipped, and appears as a flat change called a broad-based polyp. Gastric polyps are benign lesions, which are mostly treated by high-frequency electrocoagulation excision, laser, freezing, microwave cauterization, and surgery, but if left untreated for a long period of time, gastric polyps may become cancerous. When the patient has gastric polyps, it is recommended to go to the hospital in time, and the doctor will give the appropriate diagnosis according to the condition and carry out targeted treatment.
