Key Takeaways
Colorectal cancer is often preventable with routine screening. Polyps can grow silently, but screening can detect and remove them before they become cancerous.
Most adults should begin screening at age 45 — earlier if higher risk. Family history, prior polyps, or certain symptoms may require earlier or more frequent testing.
Don’t wait for symptoms. Colorectal cancer often has no early warning signs, and early detection leads to significantly better outcomes.
March is Colorectal Cancer Awareness Month — a national reminder that one of the most preventable cancers is also one of the most diagnosed.
Colorectal cancer often begins as small growths called polyps in the colon or rectum. These polyps typically cause no symptoms at first, which is why many people delay screening — especially if they feel healthy.
The good news? When detected early, colorectal cancer is highly treatable. Even better, screening can prevent cancer entirely by removing polyps before they become dangerous.
If you're 45 or older — or have certain risk factors — this month is a good time to ask: am I due for a screening?
Why Colorectal Cancer Screening Matters
Colorectal cancer does not usually cause symptoms in its earliest stages. By the time warning signs appear, the disease may be more advanced.
Screening matters because:
- Polyps can grow silently for years before becoming cancerous
- Early-stage colorectal cancer has significantly better treatment outcomes
- Removing polyps during screening can prevent cancer from developing
Unlike many cancers that can only be detected, colorectal cancer can often be prevented through timely screening.
That’s why national guidelines emphasize routine screening — even when you feel completely fine.
What Age Should You Start Screening?
One of the most common questions patients ask is: When should I get screened?
General Screening Guidelines:
- Average risk adults: Begin screening at age 45
- Family history of colorectal cancer: Screening may start earlier
- Personal history of polyps: More frequent screening may be recommended
- Digestive symptoms or unexplained anemia: Evaluation may be diagnostic rather than routine
If your results are normal and you are at average risk, screening intervals are often spaced several years apart. Your provider will help determine the right timeline for you.
If you’re unsure whether you qualify as average risk, this awareness month is a good time to clarify.
Signs You Should Not Delay Screening
While screening is recommended even without symptoms, certain warning signs require prompt medical evaluation.
Symptoms of colorectal cancer may include:
- Rectal bleeding
- Unexplained iron-deficiency anemia
- Changes in bowel habits (persistent constipation or diarrhea)
- Ongoing abdominal pain or cramping
- Unintentional weight loss
If you notice any of these symptoms, do not wait for your next routine screening window. Early evaluation can make a meaningful difference.
What Are Your Screening Options?
Several screening methods are available, and the right option depends on your medical history and risk level.
Colonoscopy
- Direct visualization of the colon
- Allows removal of polyps during the same exam
- Typically performed every 10 years for average-risk adults
Stool-Based Tests (FIT or Cologuard)
- Non-invasive
- Detect hidden blood or abnormal DNA
- Must be repeated more frequently
- Cannot remove polyps
A colonoscopy remains the most comprehensive screening option because it allows polyps to be removed during the same exam.

Why Awareness Month Is the Right Time to Schedule
Many people delay screening because:
- They feel fine
- They’re busy
- They feel anxious about the procedure
- They assume it’s complicated
Colorectal screening is typically straightforward, and the procedure itself is often completed in under an hour.
March serves as a helpful reset — a reminder to prioritize preventive health. If you’ve postponed screening in the past, consider using Colorectal Cancer Awareness Month as your checkpoint.
Preventive care works best when it’s proactive, not reactive.
