Colonoscopy Vs FIT Test – Colorectal cancer is one of the most common cancers worldwide, but the good news is – it’s highly preventable with regular screening. If you’re over 50 or are younger but have risk factors, your doctor may recommend screening tests like a colonoscopy or a Fecal Immunochemical Test (FIT).
But which test is right for you?
In this article, we’ll compare colonoscopy and the FIT test, discuss their pros and cons, and help you understand which option may be best for your situation.
Why Is Colorectal Cancer Screening Important?
Colorectal cancer often develops from precancerous polyps in the colon or rectum. These polyps can exist for years without causing symptoms. By the time symptoms like bleeding, changes in bowel habits, or weight loss appear, the cancer may already be advanced.
Screening can detect colorectal cancer early—or even prevent it by removing polyps before they become cancerous. According to the CDC, regular screening reduces colorectal cancer deaths by up to 68%.
Colonoscopy Vs FIT Test: What’s The Difference?
| Aspect | Colonoscopy | FIT Test |
|---|---|---|
| What It Is | A procedure using a flexible tube with a camera to view the entire colon. | A stool test that detects hidden (occult) blood, which may indicate cancer. |
| Preparation | Requires bowel prep (laxatives) to clean the colon. | No special prep needed—just collect a stool sample at home. |
| Invasiveness | Invasive procedure with sedation. | Non-invasive and done at home. |
| Frequency | Every 10 years (if normal). | Every year. |
| Ability to Remove Polyps | Yes, during the procedure. | No—if positive, a colonoscopy is needed. |
| Accuracy | Highly accurate—can detect polyps and cancer directly. | Good at detecting cancer but may miss some polyps. |
Pros And Cons Of Each Screening Method
Colonoscopy:
- Pros:
- Direct visualization of the entire colon.
- Polyps can be removed during the same procedure.
- Longer screening interval if normal (every 10 years).
- Cons:
- Requires bowel preparation and sedation.
- Small risk of complications (bleeding, perforation).
- Higher cost compared to FIT.
FIT Test:
- Pros:
- Non-invasive and easy to do at home.
- No bowel prep or dietary restrictions needed.
- More affordable and accessible.
- Cons:
- Needs to be done annually.
- Cannot detect polyps—only hidden blood.
- A positive result requires follow-up with a colonoscopy.
Which Test Is Right For You?
The best screening method depends on your age, risk factors, and personal preferences. Here’s a quick guide:
- Consider FIT if:
- You prefer a non-invasive test.
- You have no symptoms or high-risk factors.
- You’re unable to undergo a colonoscopy due to medical reasons.
- Consider Colonoscopy if:
- You are aged 50 and above, have no colorectal cancer risk factors, and have not done a colonoscopy within the last 7-10 years.
- You have a family history of colorectal cancer.
- You’ve had polyps in the past.
- You have symptoms like rectal bleeding, unexplained weight loss, or persistent abdominal pain.
- Your FIT test came back positive.
Pro Tip: Regardless of the method, the most important thing is to get screened regularly.
FAQs About Colorectal Cancer Screening
Q: Is a colonoscopy painful?
A: No. You’ll be sedated during the procedure and won’t feel pain. Some mild cramping or bloating may occur afterward.
Q: Can I skip colonoscopy if my FIT test is normal?
A: If your FIT is normal and you have no symptoms or high-risk factors, annual FIT testing is sufficient. However, if you’re at high risk, a colonoscopy may still be recommended.
Q: What if my FIT test is positive?
A: A positive FIT doesn’t mean you have cancer, but it does require a follow-up colonoscopy to investigate the cause of the bleeding.
Common Myths About Colorectal Cancer Screening

Fact: Colonoscopy is a safe procedure with a low risk of complications when performed by experienced doctors. - Myth: “I’m too young to worry about colorectal cancer.”
