Why Colorectal Cancer Screenings Should Start at Age 45
If you’re the type who doesn’t even like reading the fine print on a shampoo bottle, we get it — medical screenings probably aren’t high on your “fun things to do” list. But when it comes to colorectal cancer, screening is one of the most powerful tools we have to protect your health.
Why Age 45?
For many years, colorectal cancer screening was recommended starting at age 50. However, research has shown an increase in cases among younger adults, prompting major health organizations — including the American Cancer Society — to lower the recommended starting age to 45 for people at average risk.
The good news? When detected early, colorectal cancer is highly treatable, and screening can even prevent cancer by identifying and removing precancerous polyps before they become dangerous.
What Exactly Is Colorectal Cancer?
Colorectal cancer begins in the colon or rectum, typically starting as small growths called polyps. Most polyps don’t cause symptoms right away, which is why screening is so important — it finds problems long before your body starts waving red flags.
Screening Options (Yes, You Have Choices)
Not all screenings are created equal, and your provider can help you decide what fits best with your health history and comfort level.
Common screening methods include:
- Colonoscopy: The gold standard. Done every 10 years for most people, it allows physicians to detect and remove polyps during the same procedure.
- Stool-based tests: Non-invasive tests you can complete at home. Depending on the type, they may be done annually or every three years.
- Flexible sigmoidoscopy or CT colonography: Less commonly used but still effective for certain patients.
Think of screening like routine maintenance for your car — much easier to handle a small issue now than a major repair later.
Are You at Higher Risk?
You may need to start screening earlier than 45 if you have:
- A family history of colorectal cancer or advanced polyps
- Inflammatory bowel disease (Crohn’s disease or ulcerative colitis)
- Certain genetic syndromes
- A personal history of polyps
If any of these apply, talk with your primary care provider about a personalized screening plan.
Symptoms You Should Never Ignore
Even if you feel perfectly healthy, contact your provider if you notice:
- Persistent changes in bowel habits
- Blood in the stool
- Unexplained weight loss
- Ongoing abdominal discomfort
- Fatigue or weakness
These don’t automatically mean cancer — but they do mean it’s time for a conversation.
The Bottom Line
Turning 45 should come with more excitement than a screening reminder, but this is one birthday gift to your future self that truly matters. A simple test could literally save your life.
If you’re approaching 45 — or already there and fashionably late to the screening party — your primary care team is here to help you take the next step with confidence.
