Gastritis is not gastric cancer and normally will not transform into gastric cancer, but it may malign into gastric cancer.1. Gastritis refers to acute and chronic inflammation of the gastric mucosal surface, mainly due to inflammatory cell infiltration, with symptoms of digestive discomfort, manifested as abdominal distention, pain, belching, acid reflux, nausea, vomiting, constipation, diarrhea and loss of appetite. Usually, gastritis will not turn into gastric cancer.2 However, malignant lesions may occur in the gastric mucosa, and chronic atrophic gastritis is closely related to gastric cancer, which is a kind of precancerous lesion, and the clinical risk of cancer is high, especially for patients with severe atrophic gastritis. If left untreated, it can easily turn into malignant tumor and threaten the life of patients. Therefore, patients with gastritis should be treated in a timely manner, and those with severe gastritis should be examined regularly to prevent cancerous changes.
