Many people are found to have polyps during gastroscopy, and they often have such doubts: Are gastric polyps dangerous? Will they become cancerous? Gastric polyps are broadly divided into two categories: one is called adenomatous polyps, which are composed of densely arranged crowded hyperplastic glands, with varying degrees of atypical hyperplasia, the cancer rate can reach 10%-20%, known as “precancerous lesions”; the other is called hyperplastic polyps, also known as inflammatory polyps or regenerative polyps, belong to the glandular The other type is called proliferative polyp, also called inflammatory polyp or regenerative polyp, which is a prolonged proliferation of glands with disorderly arrangement, large gaps between glands, and immature cells in the middle of some of them. Most of them have no atypical hyperplasia, and the cancer rate is only 0.4%. In addition, there are polyps that are different from gastric polyps, such as juvenile polyps, which do not have a tendency to become malignant; diffuse polyps, which can have a cancer rate of 20%; and hereditary polyps. In general, gastric polyps grow very small, less than a centimeter, proliferative polyps are basically benign lesions, only a few people once the proliferative polyps grow, can cause indigestion, abdominal pain and discomfort and other symptoms, there will be upper gastrointestinal bleeding, but also cancer. Although adenomatous polyps are prone to cancer, they can also be prevented, such as epigastric discomfort, pain, nausea, loss of appetite or black stool and other symptoms, timely gastroscopy and electrodesection will be used to cut out the polyps. In order to prevent gastric polyps from becoming cancerous, we should insist on doing gastroscopy once a year to remove the polyps. In addition, to strengthen self-care, to keep the food and drink, try not to burden the stomach. As long as everyone is vigilant, stomach cancer can be kept away from the door.
