Colorectal cancer incidence and mortality have decreased in the United States in recent decades, largely through opportunistic screening. Although certain organizations have improved internal screening rates by implementing programmatic screening, most of the United States undergoes opportunistic screening. Much effort and resources have been expended comparing screening tests to determine the most effective; however, deeper analysis of the US population has revealed subsets of ethnicities may be grossly underscreened. The most effective screening test remains the test that is completed and adhered to, and a better question may concern the best method of discussing screening.
近年来，美国的结直肠癌发病率和死亡率有所下降，这主要得益于机会性筛查。尽管某些组织通过实施有计划的筛查提高了内部筛查率，但美国大多数人仍在进行机会性筛查。为了确定最有效的筛查测试，已经投入了大量的精力和资源进行比较；然而，对美国人口的深入分析表明，某些种族亚群可能严重未被筛查。最有效的筛查测试仍然是完成并坚持进行的测试，一个更好的问题可能涉及讨论筛查的最佳方法。
