An abnormal FIT result means that blood was found in the stool sample that you submitted. Abnormal FIT results are common and do NOT mean that you have cancer.
On average, ten per cent of people screened with FIT will have an abnormal result and will require additional testing. This does not mean that a cancer was found – over 96 per cent of people with an abnormal FIT result will be found to not have cancer.
Some of these patients may have polyps, which are small growths that can develop in the colon or rectum, often with no symptoms in early stages of growth. Most polyps will never turn into cancer, and for those that do, it will take many years for this transition, which is why people between the ages of 50 to 74 years should be screened regularly.
