Colon cancer is highly preventable, but only if it’s caught early. GI Consultants helps patients understand when it’s time to start screening and how to tailor that timeline based on their risk. Colonoscopy is the most effective tool available for both detecting and preventing colorectal cancer.
If you’re unsure when to schedule your first (or next) colonoscopy, this guide will help you understand the right time based on age, symptoms, and family history.
Why Colonoscopy Is The Gold Standard In Colon Cancer Screening
A colonoscopy allows your doctor to examine the full length of your colon and rectum using a flexible scope. During the procedure, polyps and abnormal lesions can be removed on the spot, reducing your risk of developing colon cancer. Sedation is used to keep you comfortable, and most people return home the same day.
Unlike other tests, colonoscopy doesn’t just detect cancer; it helps prevent it.
When To Start Colonoscopy If You’re At Average Risk
If you’re at average risk, meaning you have no personal or family history of colon cancer or polyps, and no inflammatory bowel disease or genetic conditions, you should:
- Begin screening at age 45
- Repeat colonoscopy every 10 years if your results are normal
This recommendation is supported by the American College of Gastroenterology and reflects increasing rates of colorectal cancer in younger adults.
When To Get a Colonoscopy If You’re At Higher Risk
Some individuals need to start screening earlier and need more frequent colonoscopies. You may be at higher risk if:
- You have a first-degree relative (parent, sibling, or child) who was diagnosed with colon cancer, especially if they were younger than 60 at diagnosis
- You have a personal history of colon polyps or colorectal cancer
- You’ve been diagnosed with inflammatory bowel disease, such as Crohn’s or ulcerative colitis
- You have a known genetic condition like Lynch syndrome or familial adenomatous polyposis (FAP)
In these cases, your GI specialist will recommend a personalized screening schedule, which may begin as early as your 20s or 30s, and include colonoscopies every 1 to 5 years, depending on your risk level.
Should You Get a Colonoscopy Even If You Don’t Have Symptoms?
Yes. Colon cancer often develops silently, without causing symptoms until it’s in a more advanced stage. That’s why regular screening is essential, even if you feel perfectly healthy.
However, if you do notice symptoms regardless of your age, you should speak to a GI specialist promptly.
Signs You May Need a Colonoscopy Sooner
While screening typically begins at age 45, certain symptoms should prompt earlier evaluation. These include:
- Blood in the stool or rectal bleeding
- Persistent changes in bowel habits, such as diarrhea, constipation, or narrowing of the stool
- Chronic abdominal pain or cramping
- Unexplained weight loss
- Iron-deficiency anemia or ongoing fatigue
These could be signs of colorectal cancer or another digestive condition that needs attention.
