A doctor inserting a long, flexible tube outfitted with a small camera up your rectum to examine your bowels is not a surgery that most people look forward to.<\/span><\/p>\n For years, having a colonoscopy, the second-deadliest malignancy in the world, performed on middle-aged adults has been an uncomfortable and dreaded rite of passage.<\/span><\/p>\n According to a groundbreaking study, colonoscopies may not be as helpful as they once were as a screening tool for cancer since many people still find the process to be intimidating.<\/span><\/p>\n Inviting people to a colonoscopy only reduced the risk of bowel cancer by roughly one-fifth, according to a major northern European experiment that tracked over 85,000 participants after ten years. It also did not significantly lower the chance of cancer-related death.<\/span><\/p>\n In an editorial accompanying the study, published in The New England Journal of Medicine, gastrointestinal experts described the findings as “both surprising and disheartening.”<\/span><\/p>\n Cancer advocacy organizations, however, were quick to point out the study’s flaws and stress the value of colonoscopy in finding cancer early, when it is most easily treated.<\/span><\/p>\n The reported benefits of the operation were probably diminished since only a small portion of the study participants who were invited to undergo a colonoscopy actually showed up to get one.<\/span><\/p>\n The researchers intend to repeat their analysis after 15 years because recent advancements in cancer treatments may make it too early to demonstrate a real benefit from colonoscopy screening at 10 years.<\/span><\/p>\n “Preventive cancer screenings are the best and most trusted way to save lives,” Dr Karen Knudsen, Chief Executive Officer at the American Cancer Society, said in a statement reacting to the study.<\/span><\/p>\n “That\u2019s why the American Cancer Society recommends colorectal cancer screening, colonoscopy, for adults beginning at age 45. There\u2019s no reason to change that direction. Recommended cancer screenings should be a routine part of good health”.<\/span><\/p>\n Low uptake of colonoscopies<\/span><\/p>\n The primary colorectal cancer screening test now used in the United States is a colonoscopy, which medical professionals advise having done every ten years.<\/span><\/p>\n Inversely, colonoscopy screening has not been widely used in other regions of the world, in part due to a lack of evidence from randomized trials regarding its efficacy.<\/span><\/p>\n The majority of European nations have chosen to concentrate on employing less expensive fecal immunochemical tests (FIT), which check for blood in your stool.<\/span><\/p>\n This is the first study to compare colonoscopy screening to no screening in a randomized controlled trial, which is considered the gold standard in clinical research.<\/span><\/p>\n The team, lead by University of Oslo researchers, began its research more than a decade ago, enrolling more than 84,000 participants aged 55 to 64 from Poland, Norway, and Sweden.<\/span><\/p>\n A colonoscopy invitation was sent to around 28,000 of the participants at random, while the remaining participants received their regular care, which did not involve routine colonoscopy screening.<\/span><\/p>\n The people who were invited to a colonoscopy had an 18% lower risk of colon cancer than those who were never invited to a screening, however there was no significant difference after 10 years.<\/span><\/p>\n Content created and supplied by: OEntertainment (via Opera \n , . , .
