Further testing may cause some anxiety: Screening may lead to more tests to figure out the reason for an abnormal screening test result. This does not mean a cancer was found. The majority of people called back for additional tests will not have cancer.
No screening test is perfect: Certain cancers may never cause any symptoms or affect life expectancy or quality of life. However, research shows that most colon cancers are harmful and that colon cancer should be found and treated as early as possible.
Possible concerns and impacts of screening: A
colonoscopy may be recommended for high-risk patients or after an abnormal
FIT result for an average-risk patient. There can be risks with this procedure such as bleeding and bowel perforation, and in rare cases, death.
