Colon cancer is one of the most commonly diagnosed cancers in Manitoba. People over the age of 50 are at higher risk of colon cancer. When colon cancer is detected early, it can be cured 9 out of 10 times.
If you're between 50 and 74, you should do a colon cancer screening test every 2 years.
The colon cancer screening test looks for hidden blood in the stool (poop) which can be a sign of polyps or early stage cancer. Request a home screening test today.
Colon cancer, also known as colorectal or bowel cancer, starts from polyps (small growths) in the colon or rectum. You can have these polyps for many years and not have signs or symptoms.
Most polyps do not turn into cancer. Some polyps can turn into cancer if they are not removed.
The colon cancer screening test:
To do the colon cancer screening test, collect stool (poop) samples 3 days in a row. If you do not have daily bowel movements (poops), complete the test within 7 days.
A kit will be sent in the mail once you become eligible (age 50) for colon and rectal cancer screening.
If you received a home screening test kit and did not complete it or it has expired, you can request a home screening test kit by:
If you have an abnormal home screening test result:
The colon cancer screening test is done in the privacy of your own bathroom. To do the home screening test, collect stool (poop) samples 3 days in a row. If you do not have daily bowel movements (poops), complete the test within 7 days.
Most people age 50-74 are at average risk for colon or rectal cancer and should do a colon cancer screening test every 2 years.
People of any age at increased risk for colon or rectal cancer may require additional testing. Speak with your healthcare provider to better understand your personal risk and which screening test is best for you.
Factors that impact your risk of colon or rectal cancer include a:
If you are unsure of your eligibility for ColonCheck, speak with your healthcare provider or contact ColonCheck.
Limit your vitamin C intake to less than 250 mg per day for 3 days before, and during the time you do the test. Continue to eat your usual diet except for vitamin C, as large amounts of vitamin C may hide blood that is in the stool. Click here (pdf) to read a complete list of foods that contain vitamin C.

The colon is part of your body’s digestive system (English | French (jpg)). The colon moves waste material, or things your body does not need, from the small intestine to the rectum. Together the colon and the rectum make up the large intestine (bowel).
The small intestine absorbs most of the nutrients from what you eat and then passes on the leftover waste to the colon. The colon absorbs water from the waste. What is left is called stool (feces or poop). When you have a bowel movement, the stool leaves the rectum through the anus.
It important to weigh the potential benefits and potential harms to make an informed decision about colorectal cancer screening. No screening test is perfect.
An abnormal result does not necessarily mean you have cancer. There are many possible reasons for blood in your stool. More testing will need to be done to see where the blood is coming from. A colonoscopy is usually recommended if you have an abnormal colon cancer screening test result. Repeating a colon cancer screening test after a positive result is not recommended. A positive result needs further investigation, regardless of the reason.
When a person has a positive colon cancer screening test result:
A colonoscopy allows the doctor to examine the inside of your colon (bowel) and rectum. A long flexible tube (colonoscope) with a small camera is passed into your rectum and colon. On a video monitor, the doctor looks for any abnormal areas on the lining of your colon. There can be risks with this procedure. Rarely, some people may have bleeding or other complications such as a perforation (tear) in the colon that may require a hospital stay.
Contact your healthcare provider if you experience any signs or symptoms of colon cancer such as:
