Gastric polyps have a certain probability of turning into cancer. Whether a gastric polyp will become cancerous is related to tissue typing and the size of the tumor. Gastric polyps can be clinically divided into two categories, hyperplastic gastric polyps and adenomatous gastric polyps. Gastric adenomas are the most common and have a higher risk of becoming cancerous, requiring early removal. For some asymptomatic patients, they can remain in place, and some may even regress on their own. Symptomatic hyperplastic polyps and adenomatous polyps usually have a better prognosis after gastroscopic removal and regular review to reduce the risk of cancer. Most gastric polyps are benign hyperplasia. In daily diet, patients are advised to reduce pickled food or too hot food, avoid spicy and stimulating food, eat regularly, and ensure good work and rest habits, and the prognosis is generally good. If the patient develops obvious discomfort or other symptoms, he should go to the hospital in time to see a doctor to identify the cause and then give targeted treatment.
