Is severe intestinal metaplasia cancer already?

Intestinal metaplasia of gastric mucosa is closely related to gastric cancer, but it is not gastric cancer at this stage. Intestinal metaplasia is more common in pylorus, its histological morphology, morphology and function are very similar to small intestine epithelium, and some are similar to large intestine epithelium. The specific cause of metaplasia is not very clear at this stage, and may be caused by chronic inflammation of stomach. If it is determined that there is this lesion, it needs to be actively prevented and treated. If there is chronic gastritis, it needs to be treated with gastric mucosa protection and acid suppression drugs. If there is Helicobacter pylori infection, it has to be treated with drugs for radical treatment, usually to prevent mental stress, quit smoking and limit drinking.
