As people’s standard of living and health awareness increase, more and more people are having colonoscopies at present, so the number of polyps found is significantly higher than before. Intestinal polyp is a precancerous lesion with the possibility of malignant transformation. The specific causes of colon polyps in general are not very clear at present, and are considered to be related to the following factors. First, environmental factors; second, factors of diet; third, familial factors, such as colon polyposis; fourth, consider the relationship with inflammatory stimulation. In this case, the easiest way is to perform colonoscopy, which can be used to take pathology and further treatment. If malignancy is ruled out, colonoscopic electrical resection can be performed, and if there is early cancer, colonoscopic mucosal resection can be performed, which are curable. It is recommended to review regularly after resection, about one year. The usual diet should avoid spicy, cold and other stimulating foods; appropriate exercise and drink more water.
