In the past, differences in opinion among professional groups about colorectal cancer screening have been a barrier to colorectal cancer prevention. It is clear that screening for colorectal cancer is currently practiced by fewer than 20% of American adults. However, a growing consensus now exists that even though we do not yet have trial data to compare precisely the various methods for screening, there is now both a compelling case for screening and a reasonable set of methods that clinicians and patients can consider. By applying the knowledge we already have, it is likely that most of the deaths from colorectal cancer in the United States could be prevented.
过去，专业团体之间在结直肠癌筛查问题上的意见分歧一直是结直肠癌预防的障碍。显然，目前不到20%的美国成年人进行了结直肠癌筛查。然而，现在越来越多的人达成共识，即尽管我们尚未有试验数据来精确比较各种筛查方法，但现在既有进行筛查的令人信服的理由，也有一套临床医生和患者可以考虑的合理方法。通过运用我们现有的知识，很可能可以预防美国大部分结直肠癌死亡病例。
