Abstract:

Gastric precancerous lesion refers to epithelial dysplasia (atypical hyperplasia or intraepithelial neoplasias), which is associated with increased risk of gastric cancer. It happens to be controlled by multiple factors and/or polygene such as the H. pylori infection, diet and environment which play an important role in the development of gastric precancerous lesions. This article describes the pathogenesis of gastric precancerous lesions as many scholars have studied some of it.

Key words: gastric cancer, precancerous lesions, helicobacter pylori, epithelial dysplasia
