The easy way to check for colon cancer at home
Looking for a quick, simple way to screen for colon cancer that doesn’t involve a doctor’s visit? A FIT kit might be a great option.
The information in this article is for educational purposes only and is not intended to replace medical advice from your doctor.
At one point, a colonoscopy was your only option for screening for colon cancer. That’s a type of test where a doctor inserts a flexible tube with a light and a scope on the end into your rectum. This helps them get a close look at the inside of your colon.
But then came the fecal immunochemical test, more commonly known as a FIT kit. It’s an at-home test you can take if you’re at average risk for colon cancer. Sounds like a great alternative, right?
Before you choose a FIT kit over a colonoscopy, you need to understand your risk factors because the home tests aren’t right for everyone. It’s helpful to learn more about the tests and how they work.
What does it mean if you’re at “average” risk for colon cancer?
If the five items below describe you, then you’re probably at average risk. Remember, it’s always a good idea to discuss your risk factors with your doctor, ideally at every annual wellness visit.
A yearly health and wellness assessment with a Matrix Medical Network clinician is another good time to talk about your risks and ask questions about your colon health. This visit is part of your health plan — at no added cost. Learn more about it here.
- You don’t have a personal history of colon cancer or certain types of polyps.
- You don’t have a history of inflammatory bowel disease.
- Your parents or siblings weren’t diagnosed with colon cancer before they turned 50.
- You don’t have a history of radiation treatment to the abdomen or pelvic area for a prior cancer.
- You don’t have a confirmed or suspected hereditary colon cancer syndrome such as familial adenomatous polyposis or Lynch syndrome.
What does it mean if you’re at “high” risk for colon cancer?
The following factors could mean you’re at high risk. If any of the following apply to you, your doctor may recommend a colonoscopy instead of an at-home test.
- Family or personal history of colon cancer or polyps.
- History of adenomatous polyps (growths that develop in colon tissue).
- A genetic condition known as familial adenomatous polyposis, which leads to hundreds of polyps in the colon or rectum.
- Inflammatory bowel disease (Crohn’s disease or ulcerative colitis) for at least eight years.
- Lynch syndrome (an inherited predisposition to certain cancers).
- Ovarian cancer.
- Type 2 diabetes.
Here are 9 things to know about FIT kits
If your doctor thinks that a FIT kit might be a good option for you, here are some facts to keep in mind:
1. For some people, a FIT kit is a good alternative to a colonoscopy. A FIT kit is not a replacement for a colonoscopy. But it can serve as a starting point for people with average risk factors. The American Cancer Society recommends that people who are at average risk begin screening at age 45. People in good health should continue screening through age 75. If you’re 76 to 85, ask your doctor if screenings are right for you.
Many people with average risk factors are happy to have this at-home screening option.
2. At-home colon cancer screenings need to be performed annually. Doctors suggest doing at-home colon cancer screenings once a year, not every 10 years like colonoscopies. Medicare will typically cover one FIT kit per year. If your FIT results are abnormal, you may still need to have a colonoscopy.
Again, an at-home test is a good option if you’re at average risk of colon cancer. If you’re at higher risk, doctors say a colonoscopy is the way to go. And if you’re not sure of your risk, check with your doctor to decide what’s best for you.
3. A FIT kit looks for blood in your stool. Colon cancer and polyps can bleed when stool (poop) passes by them, but you may not be able to see such small amounts of blood. This is where a FIT kit comes in: It can detect blood you might not be able to see, and it can help your doctor diagnose colon cancer earlier before it gets worse.
4. Get your FIT kit. So, you’re going to use a FIT kit? Ask your doctor to write a prescription for you then order your kit. You can pick it up at a pharmacy or have it sent to you in the mail. An even easier way to get a FIT kit is to schedule your yearly in-home health and wellness assessment. The clinician may bring the kit right to you as part of the visit.
The kit typically contains the following items:
- A collecting device
- A card or test tube
- A waste bag
- An envelope for sending your stool sample to a lab
If you have questions, check with your doctor.
5. FIT kits are noninvasive. “Noninvasive” is just a big word that means you don’t need to put any instruments inside your body. Many people appreciate that FIT kits don’t require an in-office procedure. You won’t be sedated and no special medical equipment is needed. You don’t even have to go anywhere.
6. You don’t have to do any prep. You won’t need to take laxatives or special drinks. You don’t need to restrict your diet or change the way you eat. You can take the test whenever you want.
7. It’s simple to use. Here are the steps for the FIT kit provided by your Matrix clinician:
What’s in the kit
Biodegradable collection paper (to place in the toilet bowl)
Sampling bottle with probe (to collect your sample)
Specimen bag with absorbent pad (to safely return your sample)
How to use your kit
Label the bottle with your name, date of birth, and collection date.
Place the paper on top of the water in your toilet bowl.
Have a bowel movement onto the paper.
Use the probe to take a small sample before the paper sinks.
Make sure the grooves on the probe are fully covered.
Put the probe back into the bottle and snap the green cap shut.
Flush the paper — it’s biodegradable and septic-safe.
Seal the bottle inside the absorbent pad and biohazard bag.
8. Mail the kit to a lab. Your test will need to be evaluated at a lab. You’ll send the kit in the envelope (biohazard bag) that’s provided. Your test results will go to your doctor. Results from this test are about 80% accurate.
9. Positive results from a FIT kit don’t necessarily mean you have colon cancer. If the FIT kit detects blood in your stool, your results will come back positive. But because FIT kits can’t diagnose you with colon cancer, your doctor will have you follow up with a colonoscopy. That’ll give you the most comprehensive answer.
It’s important to remember that small amounts of blood in your stool can mean many things besides cancer. For instance, the blood could be from hemorrhoids or ulcers. The most important thing to remember: Staying on top of your colon cancer screening — whether with a FIT kit or colonoscopy — could help save your life.
