In the United States, cancer screening is a complex process that involves multiple steps and can be affected by many factors, Dr. Breslau said. Needs to be done every year.

VC, Subgroup analyses for quantitative FIT and 1-sample FIT showed consistent findings supporting their accuracy; however, we could not draw any conclusions about the diagnostic accuracy of qualitative FIT or use of multiple samples due to insufficient evidence. The FIT test, or fecal immunochemical blood test, is a newer and more accurate way to test for blood in stool, which can be a symptom of colon cancer.
