The majority of stomach cancers are the result of preneoplastic lesions that have appeared several years previously. This damage is in the form of atrophy and intestinal metaplasia of the gastric mucosa caused by a prior infection due to Helicobacter pylori. Atrophy to the body of the stomach associated with intestinal metaplasia is an identified cancer risk factor. There is a beneficial effect of eradicating H. pylori seen in the evolution of this preneoplastic damage that has yet to reach the intestinal metaplasia stage. A follow-up every three years is recommended, especially for patients who have extensive or severe damage to the body of the stomach and pyloric antrum, regardless of the localisation. In cases of low grade dysplasia discovered at staging biopsies, annual follow-ups are recommended.
