The peace of mind that comes from taking control of your health is priceless. When it comes to colon cancer, early detection can be a lifesaver — and the best part? You have options. Whether you prefer a quick at-home test or the gold standard colonoscopy, HonorHealth offers screening methods that fit every lifestyle.
Deepa Shah, MD, an HonorHealth gastroenterologist, breaks down the pros and cons of each test — so you can make the best choice.
Fecal immunochemical test (FIT)
Q: What is this test?
A: Think of it as the “easy button” for colon cancer screening. It’s a simple, at-home stool test that checks for hidden blood — one of the early signs of colorectal cancer.
Q: Why consider this option?
A: There’s no need for any bowel prep or sedation, so it’s hassle-free. It’s a simple, noninvasive test — they’ll collect a stool sample at home. Plus, it’s 79% effective at detecting colorectal cancer.
Q: Are there any downsides?
A: This test isn't great at picking up smaller polyps, and sometimes it can give false-positive results. If it comes back abnormal, we may recommend a colonoscopy to take a closer look.
Q: How often should you take this test?
A: Once a year, starting at age 45.
Q: Is it covered by insurance?
A: Usually, but check with your provider just to be sure.
Multitarget stool DNA test
Q: What is this test?
A: It’s like the fecal immunochemical test, but with a little extra power. This at-home test checks for both blood and abnormal DNA that could indicate colorectal cancer.
Q: Why consider this option?
A: There’s no bowel prep or sedation involved — it's as simple as collecting a sample at home. It’s more sensitive than the FIT test, with 92% effectiveness at catching colorectal cancer.
Q: Are there any downsides?
A: It can sometimes give false-positive results and isn't the best at spotting smaller polyps. If your results come back abnormal, you'll need a colonoscopy.
Q: How often should you take this test?
A: Get it every five years, starting at age 45, to stay ahead and keep your health in check.
Q: Is it covered by insurance?
A: It might not be, but it’s always a good idea to check with your insurance plan to find out.
CT colonography/virtual colonoscopy
Q: What is this test?
A: Think of it as a colon screening without the camera. A CT scan gives detailed images of your colon — no scope and no sedation needed.
Q: Why consider this option?
A: It’s super quick and it takes about 15-20 minutes. There’s no sedation needed, and it can detect polyps as small as 1 centimeter with 90-95% accuracy.
Q: Are there any downsides?
A: You’ll need to do some bowel prep for this one, and it uses a small amount of radiation. If anything suspicious shows up, though, you’ll still need to follow up with a traditional colonoscopy for a closer look.
Q: How often should you take this test?
A: Every five years, starting at age 45.
Q: Is it covered by insurance?
A: Coverage varies since this is a newer test. Check with your provider.
Colonoscopy (the gold standard)
Q: What makes a colonoscopy the best option?
A: It’s the most thorough way to screen for colorectal cancer. A doctor uses a tiny camera to examine your entire colon — and can remove polyps on the spot before they become cancerous.
Q: Why consider this option?
A: It gives a full view of your colon, so there’s no guesswork involved. If we find any polyps, we can remove them right there during the test — no need for a second procedure. It can also help detect other diseases and cancers.
Q: Are there any downsides?
A: You’ll need to do some bowel prep for this one, and it uses a small amount of radiation. If anything suspicious shows up, though, you’ll still need to follow up with a traditional colonoscopy for a closer look.
Q: How often should you take this test?
A: Every five years, starting at age 45.
Q: Is it covered by insurance?
A: Most insurance plans and Medicare cover it, but it’s more expensive than other tests.
