目的：本研究的目的是，看看是否个人认为他们的风险发展为结直肠癌（CRC）低于平均水平被发现是在较低的风险，确定在灵活的乙状结肠镜检查（FS）screening.Methods的结果：参与者（n=10,551）是男性和女性，年龄55-64岁，从一个子集的参与者在英国FS试验。在参与者被邀请参加FS筛查之前，自我报告问卷评估了发生肠癌的相对风险。客观风险判断息肉状态FS test.Results：一个非常温和的关系，发现风险判断和实际风险与77%的“乐观主义者”有负面的结果相比，71%的“悲观主义者”。与乐观者（11%）相比，悲观者（14%）患有腺瘤。与悲观主义者相比，乐观主义者患结直肠癌的风险较低的几率为0.70（0.57，0.86）。结论：结果表明，人们评估其患结直肠癌风险的能力可能有限。卫生专业人员不应该假设个人对他们患癌症的风险有准确的认识。提高人们准确感知风险的能力可能会鼓励更适当的癌症预防行为。
Objective: The aim of this study was to see whether individuals who perceive their risk for developing colorectal cancer (CRC) as lower than average are found to be at lower risk as determined by findings at flexible sigmoidoscopy (FS) screening.Methods: Participants (n=10,551) were men and women aged 55-64 years from a subset of participants in the UK FS Trial. Self-report questionnaires assessed perceived comparative risk of developing bowel cancer prior to participants being invited to attend FS screening. Objective risk was judged from polyp status during the FS test.Results: A very modest relationship was found between risk judgments and actual risk with 77% of 'optimists' having negative findings compared to 71% of 'pessimists'. More pessimists (14%) had an adenoma compared to optimists (11%). Compared to pessimists the odds of optimists actually being at lower risk of CRC equaled 0.70 (0.57, 0.86).Conclusions: The results suggest that people may have a limited ability to assess their risk of developing CRC. Health professionals should not assume that individuals have an accurate perception of their risk for cancer. Increasing people's ability to accurately perceive their risk may encourage more appropriate cancer preventive behavior.
