Colorectal Cancer: Who Needs a Colonoscopy and When
Colorectal cancer screening guidelines are vital for early detection and prevention. Here's a rundown of who needs a colonoscopy and when, based on recent recommendations and risk factors.
Everyone should have their first colonoscopy by 50, regardless of gender or overall health. However, those with a family history of bowel cancer, IBS, IBD, or colorectal polyps may need to start earlier, even at 45.
Individuals with ulcerative colitis should undergo a colonoscopy every 2 to 5 years, due to an increased cancer risk around 8 to 10 years post-diagnosis. Those with diverticulosis typically need one every 5 to 8 years, depending on symptom severity.
After a polypectomy, a follow-up colonoscopy is recommended at least 5 years later. Conversely, after age 75, routine colonoscopies may be discontinued due to potential complications.
The U.S. Preventive Services Task Force is considering lowering the first colonoscopy age to 40 or below. Regular stool testing every two years, or a colonoscopy with an option for two colonoscopies at least ten years apart, is recommended for those with no increased risk.
Regular colonoscopies, tailored to individual risk factors, are crucial for colorectal cancer prevention. Stay informed about the latest guidelines and consult your doctor for personalized advice.
