Gastrointestinal polyps do not necessarily need to be removed. For polyps that are small in size and have no risk of becoming cancerous, follow-up observation is the mainstay. If the size of the polyp increases rapidly, or if cancer is suspected, it should be surgically removed as soon as possible. The appearance of polyps in the stomach and intestines is mainly considered to be related to diet, inflammatory stimulation and genetic factors. For asymptomatic polyps that are small in size and have little or no risk of cancer, no special medical treatment can be taken for the time being, and only regular follow-up and observation is needed. For patients with larger polyps, rapidly developing polyps, and those with a tendency or high suspicion of cancer, they should be examined as soon as possible and treated with endoscopic polypectomy, for example. Different patients have different degrees of disease, and whether surgery is needed should be arranged by the doctor after examination and diagnosis.
