20 Steps to Master the Art of Surviving Your First Colonoscopy
11. Colonoscopies Can Be Preventative, Not Just Diagnostic
One of the most powerful—and often overlooked—benefits of a colonoscopy is that it’s not just designed to find colon cancer, but also to prevent it entirely. During the procedure, doctors can detect and remove polyps, which are small growths on the inner lining of the colon. While most polyps are benign, some can gradually become cancerous if left unchecked. By removing these polyps on the spot, a colonoscopy interrupts the disease before it even begins. That makes it one of the few cancer screening tests that actually reduces your future risk of developing cancer. Unfortunately, many people delay the test, assuming it’s only needed when symptoms arise. But by then, polyps could have progressed to more serious stages. Early and regular screenings are crucial. When done on schedule, colonoscopies have the potential to save thousands of lives each year by stopping colorectal cancer in its tracks—before it ever has a chance to grow.
12. You May Be Awake—But You Won’t Remember It
If the idea of being fully awake during a colonoscopy makes you nervous, you’re not alone—but here’s the reassuring truth: most colonoscopies are performed using conscious sedation, which means you’re technically awake, but deeply relaxed and unlikely to remember anything about the procedure. You'll be drowsy, calm, and pain-free, often drifting into a twilight state where time passes quickly. The combination of sedatives and pain relievers ensures that you feel little to no discomfort while remaining safe and responsive if necessary. Some patients opt for deeper sedation or general anesthesia, which results in complete unconsciousness, while others—especially in certain countries or with virtual colonoscopies—choose to forgo sedation altogether. Your provider will discuss the best option based on your health history, anxiety level, and preference. The key takeaway? Even though you're not technically "asleep," most people are pleasantly surprised by how easy and forgettable the experience actually is.
