Colon Cancer Screening: When Should I Schedule a Colonoscopy?

Screening for colorectal cancer is one of the most effective ways to detect and prevent the disease before it becomes serious. In response to the rising number of cases in younger adults, national health guidelines now recommend starting routine colonoscopy screenings at age 45—five years earlier than previous recommendations. This earlier start helps doctors detect and remove polyps before they become cancerous, improving the chances of catching cancer early or preventing it altogether. At Lane Gastroenterology, we work closely with patients to create personalized screening plans tailored to individual risk factors, such as family history or chronic conditions, all while prioritizing comfort, clarity, and expert care.

What Happens During a Colonoscopy?

A colonoscopy is a painless, outpatient procedure that lets your doctor examine the inside of your colon using a thin, flexible tube called a colonoscope. The procedure typically takes 15 to 60 minutes, depending on whether polyps are found and removed during the procedure.

Our specialists at Lane aim to make the process as stress-free and straightforward as possible. During the exam, your doctor views images on a screen, removes any abnormal growths, and may take biopsies if needed. Once the procedure is complete, you’ll have time to recover and then review your results with your care team.

What Are the Warning Signs That I Should Get a Colonoscopy?

Routine screening usually begins at 45, but you may need one sooner if you experience:

• Blood in your stool
• Unexplained abdominal discomfort
• Ongoing changes in bowel habits
• Unintentional weight loss
• A family history of colorectal cancer or polyps
• Conditions like Crohn’s disease or ulcerative colitis

If any of these apply to you, don’t wait. Lane’s team can help you determine whether early screening is a good fit and guide you through the next steps.

How Do Colonoscopies Prevent Colon Cancer?

Colonoscopies do more than diagnose; they help prevent cancer. Most colorectal cancers originate from polyps, which typically grow slowly over time. By removing them early, your doctor can stop cancer from developing altogether. In many cases, a clear result means you won’t need another screening for ten years. It’s a quick, preventive measure that supports your health now and helps you stay ahead of potential problems down the road.

Are There Alternatives to Colonoscopy for Colon Cancer Screening?

For those who prefer a less invasive option, there are alternative screening tests such as at-home stool tests or imaging scans. While these can be effective in some cases, they aren’t as thorough as a colonoscopy. If something abnormal is found, a follow-up colonoscopy is usually needed. You don’t have to decide alone. Lane’s team is here to help you understand your options and choose what’s right for you.

If you’re approaching 45 or have questions about your risk for colorectal cancer, it may be time to talk to your doctor about screening. A colonoscopy offers a reliable way to catch potential issues early and prevent cancer before it starts. At Lane Gastroenterology, our team is here to make the process comfortable and straightforward. From your initial consultation to any follow-up care, we provide the support you need to navigate your health journey confidently.
