This is the part about asking your doctor. If you have a family or personal history that puts you at higher risk of colon cancer, an annual FIT screening may not be for you. Bear in mind that the FIT screening looks for blood in the lower GI tract. Blood can come from colon cancer, polyps and some other causes. If the FIT screening detects blood, a followup colonoscopy is done. If you have polyps, many providers recommend a colonoscopy instead since a suspicious-looking polyp can be removed right then and there.
And in recent years, the FIT tests have gotten way more accurate at detecting blood.
