Single gastric polyp and multiple gastric polyp are different in terms of the number of polyps, the chance of cancer, and treatment modalities. 1. Difference in number: single gastric polyp refers to a single number of polyps in the stomach, while multiple gastric polyp refers to two or more gastric polyps. 2. Different chances of cancer: single gastric polyp is a benign lesion, the chances of cancer are not very high, but there is a risk of cancer. Multiple gastric polyps have a higher chance of cancer. 3. Difference in treatments: The initial symptoms of solitary gastric polyp are not obvious, so it does not need special treatment. However, regular observation is needed. When the symptoms of solitary gastric polyps are obvious, endoscopic surgery is needed to remove them. Multiple gastric polyps usually need to be treated by endoscopic resection. If any of the above situations occurs, it is recommended to go to the hospital in time, under the guidance of professional physicians to clarify the specific treatment plan.
