How Often Do You Need a Colonoscopy?
Almost everyone has heard stories about colonoscopy prep. Drinking the solution, changing your diet, and spending the day in the bathroom aren’t exactly something people look forward to. If you’re approaching age 45 or your doctor has recommended a colonoscopy, you may be wondering if this is something you’ll have to do every year.
How often do you need a colonoscopy? The answer depends on your age, your risk factors, and the results of your exam. While some people need more frequent screenings, many people with normal findings won’t need another colonoscopy for 10 years.
When Should Colon Cancer Screening Begin?
For adults at average risk of colorectal cancer, screening usually begins at age 45. However, some people need to start earlier. This includes people with:
- A personal history of colon polyps
- A strong family history of colorectal cancer
- Inflammatory bowel disease involving the colon
- Certain inherited cancer syndromes
- A history of abdominal or pelvic radiation
While stool-based screening tests are also available, colonoscopy remains the gold standard. It allows your doctor to examine your entire colon and remove polyps during the same procedure. If a stool test finds something abnormal, you’ll still need a colonoscopy to find the cause.
How Often Do You Need a Colonoscopy After Normal Results?
If your colonoscopy is normal, that’s good news. Research shows your risk of colorectal cancer usually stays low for many years after a normal exam.
For most people at average risk with no polyps or other concerning findings, the next colonoscopy is recommended in 10 years.
This long screening interval is one reason colonoscopy is such an effective screening test. During the procedure, your doctor can find and remove many polyps before they become cancerous. If your results are normal and you don’t develop new symptoms, you can usually wait 10 years before your next screening.
How Often Do You Need a Colonoscopy If Polyps Are Found?
Polyps are growths that develop on the lining of the colon. While many are harmless, some can become cancer over time.
If polyps are found, you may need another colonoscopy sooner than 10 years. Your doctor will consider:
- How many polyps were removed
- Their size
- The type of polyps
- Whether they showed precancerous changes
Your gastroenterologist will recommend the right screening schedule based on your results and medical history.
You May Need a Colonoscopy Sooner If You Have Symptoms
Screening isn’t the only reason someone may need a colonoscopy. Your doctor may recommend one if you develop symptoms such as:
- Rectal bleeding
- Blood in the stool
- Unexplained iron-deficiency anemia
- Persistent abdominal pain
- Unexplained weight loss
- Ongoing changes in bowel habits
If you’re having symptoms, don’t wait until your next routine screening. Your doctor may recommend a colonoscopy sooner to find the cause.
Do Older Adults Need Colonoscopies?
For many adults, routine colorectal cancer screening continues through age 75.
Between ages 76 and 85, the decision becomes more personal. Your doctor will consider factors such as:
- Your overall health
- Your previous colonoscopy results
- Your personal preferences
If you’ve had regular screenings with normal results, your doctor may decide that you don’t need additional colonoscopies. Talk with your doctor about what’s right for you.
What Happens If You Wait Too Long?
It can be tempting to put off a colonoscopy, especially if you feel healthy. The problem is that colon polyps and early colorectal cancer often don’t cause symptoms.
Waiting too long may give a precancerous polyp time to grow. Following your doctor’s recommended screening schedule gives you the best chance of finding problems early, when they’re often easier to treat.
How Often Do You Need a Colonoscopy?
How often you need a colonoscopy depends on your age, your personal risk for colorectal cancer, your previous colonoscopy results, and whether you develop symptoms. While some people need colonoscopies more often, many people with normal results won’t need another exam for 10 years.
