Multiple rectal polyps are usually not serious. However, multiple rectal polyps that are large, numerous or hereditary are more serious. Multiple rectal polyps are mainly mucosal redundant growths in the intestines after the intestines are stimulated by inflammation. If the size is small and the number of multiple rectal polyps is small, the result of the pathologic examination is benign, and the patient usually does not have any discomfort and is usually not serious. If the number of multiple rectal polyps is large, still growing, and accompanied by other symptoms, such as blood in the stool, mucus stool, polyp prolapse, etc., do not rule out the possibility of cancer, such as rectal cancer, this is more serious. If it is hereditary multiple rectal polyps, the probability of malignant transformation is higher, which is a more serious disease. Early symptoms of multiple rectal polyps are not obvious, as long as the earliest possible surgical resection treatment, post-operative pathological examination, and regular review, generally there will not be major problems. Therefore, patients with multiple rectal polyps must pay attention to regular review and active treatment.
