Colon polyps are bulges that rise from the epidermis of the colonic mucosa and protrude into the lumen. Since the 1970s, the detection rate of GI polyps has been greatly improved due to the advancement of endoscopy, X-ray, ultrasound and other examination techniques. Because they generally have no clinical symptoms, only a small percentage of patients with intestinal polyps clinically present with abnormalities such as blood in the stool, mucus stool, and abdominal pain, and these symptoms often lack specificity, so to confirm the diagnosis of intestinal polyps, we have to rely on instrumental examinations such as colonoscopy. The former is caused by proliferative inflammation of the intestine and is almost not malignant; adenomatous polyps have a higher chance of malignancy than inflammatory polyps, and adenomas are recognized as precancerous lesions. Adenomas are classified as tubular adenomas, villous adenomas, and mixed adenomas, with the highest cancer rate in villous adenomas and the lowest rate in tubular adenomas. Adenoma may be related to genetics, chronic inflammatory irritation, lifestyle habits, chronic constipation and other factors. Colonoscopy can not only detect early intestinal cancer, but also distinguish the nature and size of intestinal polyps, according to which doctors can directly perform simultaneous painless removal of high-risk intestinal polyps, and patients can leave on their own after only about one hour of rest, which greatly reduces the chance of patients becoming cancerous. Polyps can recur and should be reviewed regularly In cases where polyps are very small (less than 0.3cm in diameter) and many of them are difficult to be detected and removed all through colonoscopy, patients usually need to be reviewed regularly. However, some patients have their intestinal polyps cut cleanly at one time and the polyps are benign after pathological examination, so these people often do not care much about regular re-examinations. This attitude is not beneficial to the prevention of bowel cancer. Intestinal polyps are not cut once, they may recur again, and the location and nature of their occurrence may be different. Therefore, any patient who has a history of intestinal polyps should be reviewed. If there is only one polyp and the pathology proves to be benign, the colonoscopy should be checked only once a year at the beginning and no recurrence for 2-3 consecutive years, and then it can be changed to once every three years. The westernized high-fat and high-protein diet is prone to colon polyps, while the increasing high-fat and low-fiber dietary patterns in China may be an important reason for the increased incidence of colon cancer. Our traditional diet is richer in plant fiber than the Western diet. Eating more green leafy vegetables, tomatoes, eggplants and carrots is beneficial to intestinal motility and reduces the occurrence of polyps.
