Gastric fundal polyps are generally not cancerous. Fundic gland polyp is a common type of gastric polyp, which is a benign elevated lesion originated from the gastric mucous membrane layer of the fundus and protrudes into the gastric cavity, and sporadic fundic gland polyp is almost never cancerous. Gastric fundus polyps may be related to heredity, Helicobacter pylori infection, bile reflux, and chronic inflammatory stimulation. Most patients do not have specific clinical manifestations, and may sometimes have gastrointestinal symptoms such as abdominal discomfort, heartburn, vomiting, and bloating. Gastroscopy is the preferred diagnostic method, in which the size, type and severity of the polyp can be clarified, and biopsy can be performed to further clarify the nature of the polyp if necessary. Gastric fundus polyps should be diagnosed in a timely manner in hospitals and intervene under the guidance of specialized physicians to avoid delaying the condition.
