Further testing may cause anxiety: Screening may lead to more tests to figure out the reason for an abnormal screening test results. This does not mean cancer was found. The majority of people called back for additional tests will not have cancer.
No screening test is perfect: Screening finds many non-cancerous polyps and colon cancers, but no screening test is perfect. Regular screening offers the best chance of finding the early signs of cancer.
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.
