What causes a positive FIT result?

A positive FIT result means that blood was detected in your stool sample. Blood in the stool can be caused by conditions other than colorectal cancer such as colon polyps, inflammation, ulcers, fissures, hemorrhoids, straining when giving the sample, and certain medications. It’s important to follow up with your healthcare provider to talk about your results. Your healthcare provider can help you make a plan to best manage your health.
