29 may is world intestine health day. The intestinal tract is like the “second brain” in the body, but colon cancer is the second highest incidence of malignant neoplasms in the country, with more than 550,000 new cases per year. In 2024, more than 240,000 people died of colon cancer。
The development of colon cancer is slow, and the early and even pre-cancer stage (e. G. Salivating flesh) of enteric cancer may be unsymptomatic, and the optimal intervention period is often missed when the body signals. In addition, our early screening rate for colon cancer has been low。
“first screening is important for the prevention and treatment of colon cancer.” on 28 may, professor lee xiaobo, director of the indigestion insight centre of the hospital, affiliated with the medical school of the shanghai university of transport, in an interview with the daily economic news journalist, recommended that ordinary men should undergo their first intestine examination from the age of 40 and that women should be deferred to the age of 45; those with family history, obesity, diabetes or high diets should be screened earlier。

“many people think it's all right to eat and drink, and that abdominal pain and blood are necessary for medical treatment, which may be mid-term and late.” according to lee xiaobo, the vast majority of intestinal cancers have evolved from lower upper-skinned cancers to higher-skinned cancers over time, at a time when the risk of cancer has increased significantly。
The incidence of intestinal cancer can be significantly reduced if patients undergo intestinal osmosis at a lower stage. From clinical data, early intestinal cancer (limited to the mucous membranes) has a five-year survival rate of over 90 per cent, but when symptoms such as abdominal pain, consecration, anaemia and so forth, approximately 70 per cent of the patients have advanced cancer, with a five-year survival rate of less than 30 per cent。
Lee xiaobo mentioned that special light technology and ai-aided diagnostics introduced in recent years with the representation of the interior mirror of the country could help doctors to see hidden, difficult-to-detect pathologies and reduce the failure rate of newcomers. When early cancer stoves are fully removed under the intestinal lens, the patient can completely avoid abdominal surgery and subsequent chemotherapy. He hoped that attention would be paid to early screening for intestine cancer and that clinical benefits would be evident。
Journalists have also learned that the later colon cancer is discovered, the higher the cost of treatment. Intestine cancer in the period of progress requires surgically enhanced chemotherapy at a cost of over $100,000. However, if an adenoma is detected at an early stage, it can only be removed through an endoscope at a cost of less than $1,000。
“the results of the first inspection often determine the future pace of monitoring and the path to cancer risk control.” he suggested that the first colonoscopy screening should be initiated for men from age 40 and women from age 45. For groups with family history, the first screening is 10 to 20 years ahead。
The review time for colonoscopy also varies from person to person. According to lee xiaobo, under normal circumstances, persons over 50 years of age at low risk can be examined every five years. The quantity, diameter, type of tissue (e. G., velvet adenoma) and the presence of a high-level epidemioma are key factors in determining the interval between reviews, and doctors arrange follow-up visits according to their level of risk。
In the case of stench meat found above one centimetre, velvet composition above 25 per cent or upper periphery tumours, one year's review is required; at the lower stage, the patient can review for three to five years。
Early screening for enteric cancer was introduced many years ago at the mercy hospital, affiliated to the medical school of shanghai university of transport. In 2009, through the china-japan cooperation project, the centre trained the first group of early cancer diagnostic specialists, and through its youth mentors trained local doctors, a three-tier training system for “centre mentors—provincial mentors—local doctors” was developed, with over 20,000 doctors being trained. Following the radiation from the training network at the hospital, the population has increased its recognition of the hospital and its increasing number of consultations, reaching a total of over 300,000 cases last year。
“we now treat early tumour pathologies in the oesophagus, stomachs and intestinal tracts with endoscopy, and through these screenings many early cancer patients have indeed been detected.” according to lee, screening for early cancers is time-consuming and labour-intensive, and many hospitals are still trying to do this, but this is of great significance. Prior to 2009, patients were surgically excised as long as there was a “cancer” diagnosis. The technology is now capable of removing tumours of about two millimeters, and for the patient, the function of the organ has not been affected at all and there are no visible wounds to the body。
Nevertheless, it is unfortunate that lee xiaobo is still clinically witnessing an increasing number of men aged 30 and 40 who have been diagnosed with mid-to-late intestinal cancer, many of whom wait until they have abdominal pain and abdominal blood to be examined. Although many more young people than 10 years ago volunteered to perform intestinal examination, there was, in general, a cognitive error in intestinal lenses。
“first of all, i think it is important to correct the diagnosis of symptoms, and some people are wrong to see blood tests showing normal signs of intestinal tumours and feel safe and healthy. There are also those who feel that the laxatives cannot go on, fear the anesthesia, fear the memory, and need our help to overcome these confusions and fears and not resist gastrointestinal examination.” according to lee xiaobo, the laxatives, narcotic drugs and methods before intestinal examination are constantly being optimized over the years。
In order to improve intestinal cleanliness, laxative companies are constantly pushing for better and more effective products to alleviate the fear that people cannot drink. In addition, the use of intravenous anesthesia in painless intestines is safe and effective and does not affect memory。
According to lee xiaobo, greater awareness and awareness-raising are necessary for early screening for colon cancer. He was also convinced that a colonoscopy examination would provide health security for the following years and would be accepted as the most direct and effective form of examination。
In addition, upgrading screening capacity in primary health-care institutions is crucial. The current rate of development of the domestic digestive endoscopy is rapid and relatively low, and the technical functionality is gradually catching up and even exceeding the imported equipment. This has a considerable role to play in the universalization and grass-rootsization of endoscopy. When each district hospital has a high-quality endoscope, the rate of early detection will be a real breakthrough。
