Colon cancer is on the rise globally, but there’s a powerful, simple tool that saves lives: the colonoscopy
Colorectal cancer remains one of the world’s most deadly cancers, with projections showing millions of new cases and deaths in the coming years. The World Health Organization highlights a troubling 1.6 million deaths and 3.2 million new cases by 2040, a rise of about 73% from today. Yet, experts insist that early detection can dramatically improve outcomes. One quote that stands out in the current conversation comes from Dr. Emmanuel Aguh, a board-certified family medicine physician in the United States, who emphasizes a single, life-saving test: the colonoscopy.
Why colonoscopy matters
A colonoscopy is not just about diagnosing cancer; it’s a preventative procedure. During a colonoscopy, a physician examines the entire colon for polyps—small growths that can become cancerous over time. If precancerous polyps are found, they can be removed right then, often preventing cancer from developing in the first place. This proactive approach is what makes colonoscopies one of the most effective tools in reducing new colon cancer cases and deaths.
What Dr. Aguh says about the test
Dr. Aguh acknowledges that the idea of a colonoscopy can feel daunting. He stresses honesty: modern colonoscopies are typically performed under sedation, meaning most patients do not remember the procedure and feel little to no discomfort. The temporary unease is a small price for the potential to save a life. He also reminds readers that while an average-risk person might wait until age 45 or later to begin routine screening, concerning symptoms or risk factors can prompt earlier evaluation.
When to consider screening
Screening guidelines often start discussions around age 45 for average-risk individuals, with earlier starts for those with a family history, inflammatory bowel disease, or other risk factors. Dr. Aguh notes that symptoms like persistent changes in bowel habits, blood in the stool, unexplained abdominal pain, or unexplained weight loss warrant prompt medical attention and potentially earlier testing. The key takeaway is personal risk matters: discuss with your doctor to determine the right starting point for screening.
Addressing fears and promoting action
The emotional hurdle—fear of the procedure or misinformation—appears frequently. Dr. Aguh’s guidance is clear: don’t let fear delay life-saving screening. A colonoscopy is a routine procedure for many people and is performed in a controlled, medically supervised setting. The reward is the chance to catch cancer at an early, more treatable stage or, ideally, to prevent it entirely by removing polyps before they become problematic.
What to expect with a colonoscopy
Preparation is a part of the process, but the actual procedure is relatively quick and conducted with sedation. After the procedure, most patients feel minimal discomfort and can resume daily activities soon after. If polyps are found, they are typically removed during the same session. For those anxious about the idea of a camera traveling through the colon, remember that early detection is a proven strategy to reduce mortality from colon cancer.
Take action today
As Dr. Aguh emphasizes, screening is a powerful, practical step you can take today. If you’re due for a colonoscopy or have risk factors that warrant earlier screening, schedule an appointment with your primary care physician or a gastroenterologist. Regular screening aligns with the goal of reducing colon cancer deaths and catching cancer early when treatment is most effective. Your future self will thank you.
Bottom line
Colon cancer is a major public health concern, but it is largely preventable through routine screening and early detection. A colonoscopy offers a direct path to identifying and removing precancerous polyps, and for many, a successful early cancer diagnosis. Talk to your doctor about when to start screening and how to prepare for the test.
