When most people think of a colonoscopy, they picture it as a test to find problems in your colon. In reality, a colonoscopy is one of the most powerful tools we have in preventive care—it doesn’t just detect colon cancer, it can actually help prevent it.
Colorectal cancer is the second leading cause of cancer death in the United States. Most cases begin as small, noncancerous growths called polyps. During a colonoscopy, your doctor can find and remove these polyps before they ever turn into cancer. This means the procedure is both diagnostic and therapeutic, when it removes cancers, but a colonoscopy is both diagnostic and preventative, when it removes polyps. Isn’t that awesome?
Average-risk adults: Begin screening at age 45 (earlier if you have risk factors like family history, inflammatory bowel disease, or genetic syndromes).
Repeat screening: Typically every 10 years if no polyps are found, though your doctor may recommend more frequent exams depending on results.
Benefits Beyond Cancer Prevention
Detects other conditions like diverticulosis, colitis, or sources of unexplained bleeding. Note that colonoscopy is not a standard test for constipation, even though most people will get a colonoscopy for constipation issues.
Provides peace of mind with a clear picture of your colon health.
Guides personalized care based on your individual risks.
A colonoscopy is more than a random test—it’s a chance to stop colorectal cancer before it starts. If you’re 45 or older, or have risk factors, talk to your doctor about scheduling one. Preventive care today can mean a healthier gut tomorrow.
Until next time, that’s just the way the anus wrinkles.
