Progress in clinical diagnosis and treatment for gastric polyps.

Gastric polyps are common precancerous diseases. With the intensive study on the characteristics of different types of gastric polyps in recent years, only 1.7% of the gastric polyps were found to have dysplasia and cancer, and most of the dysplasia and cancer were found in polyps larger than 1 cm. Traditional idea suggests that polyps should be removed immediately, but routine removal of all polyps results in an increased financial burden on patients. At present, there are controversies about whether endoscopic treatment is necessary for different pathological types and small gastric polyps.
