The UK Breast Screening Programme intends to introduce two-view screening on all screening rounds, and also to extend the normal screening age range at its upper end from the present 64 years to 70 years. The implications of these changes for cancer detection:induction ratios and for benefit/risk ratios are discussed. It is shown that both ratios remain much greater than 1.0 at all screening ages. This is also true for younger women, subject to provisos regarding starting ages for annual screening as described in previous papers. The requirements for optimization in a breast screening programme are also discussed. It is suggested that benefit (rather than the benefit/risk ratio) should be maximized provided that benefit exceeds risk.
英国乳腺癌筛查计划打算在所有筛查轮次中引入双视角筛查，同时将正常筛查年龄范围的上限从目前的64岁延长至70岁。讨论了这些变化对癌症检测的诱导率以及获益/风险比的影响。结果表明，在所有筛查年龄，这两个比率都远大于1.0。对于年轻女性也是如此，但需遵循先前论文中所述的年度筛查起始年龄的相关条件。还讨论了乳腺癌筛查计划中的优化要求。建议在获益超过风险的前提下，应使获益（而非获益/风险比）最大化。
