Everyone is at risk in front of cancer, but many people still lack vigilance to precancerous lesions. Two years ago, Old Wang showed symptoms of diarrhea, abdominal pain and blood in stool. At first, he was very nervous and worried about intestinal cancer, but the colonoscopy found two intestinal polyps, which were confirmed by biopsy to be benign adenomatous polyps of the large intestine, and since then, he left the medical advice of “regular review” behind. Experts point out that intestinal polyps are precancerous lesions of colon cancer, and many patients do not pay enough attention to them and are unwilling to conduct necessary colonoscopy for early detection of polyps, and even unwilling to take care of those who have had polyps removed. This attitude increases the risk of bowel cancer. Colorectal polyps must be removed Colorectal polyps are commonly known as lumps of meat growing on the wall of the large intestine. The former is caused by proliferative inflammation of the intestine, while the cause of the latter is unknown and may be related to genetics, chronic inflammatory stimulation, lifestyle habits and other factors. Adenomatous polyps do not go away on their own, and if left untreated, they can grow slowly and have a higher probability of malignancy; while inflammatory polyps are relatively safer, and sometimes very small inflammatory polyps will disappear on their own, but inflammatory polyps may become cancerous when stimulated by inflammation for a long time. Usually the nature of the polyp is not clear in the fashion of colonoscopy, generally are immediately removed endoscopically, for those who can not be removed, such as the tumor is too large, the growth site is not convenient to remove, to further treatment through surgery and other methods. ”The general endoscopic removal of polyps is not a major surgery, the patient does not even need to be hospitalized, polypectomy can be done in the outpatient clinic.” Colonoscopy is both the most effective method of examination and an extremely convenient treatment. “Only pathological examination can confirm the nature of polyps and the probability of cancer, providing an important basis for bowel cancer prevention and treatment.” Polyps are prone to recurrence 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 detect and remove all of them 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 for 2-3 consecutive years without recurrence, after that it can be changed to once every three years. However, if there are multiple benign polyps, for insurance purposes, it is still necessary to have a colonoscopy once a year. If cancerous polyps are found, more frequent review should be performed after removal; if the polyp root is cancerous, further surgical treatment must be done”. Eating more veggies is beneficial in reducing the occurrence of polyps From experience, many patients with intestinal polyps prefer meat. Although this is just a phenomenon, studies have proven that a westernized lifestyle may be an important cause of the increased incidence of colorectal cancer. And intestinal polyps are precancerous lesions of colorectal cancer; therefore, not eating more meat but more vegetarians is good for cleaning up intestinal toxins and preventing polyps, which in turn reduces the chance of colorectal cancer. ”The so-called vegetarian diet is generally valued for vitamins and fiber. If you take into account the nutritional aspects, you can eat more dark vegetables, such as green leafy vegetables, tomatoes, eggplants, carrots, etc. In addition, more fruits with better laxative effect such as plantains, pears and kiwis should be consumed.” People with chronic constipation should eat more vegetarian food, because constipation can lead to excessive absorption of toxins, which is not good for health. But the importance of eating vegetarian is not the same as not eating meat, but also can not go to the other extreme, it is appropriate to meat and vegetarian, mainly vegetarian.
