To examine the effect of using two view mammography in comparison with one view mammography in the detection of small (< 15 mm) invasive cancers.
Screening programme data from National Health Service breast screening programme (NHSBSP).
Data were collated from all screening programmes in the United Kingdom on standard "Korner" returns (KC62 forms) for the screening year 1 April 1994 to 31 March 1995. The comparison of invasive cancer detection rates by programmes using one and two view mammography with indirectly age standardised invasive cancer detection rates.
Programmes using two views for women attending their prevalent screen (first screen) in the NHSBSP detected 3% more non-invasive/microinvasive cancers, 7% more large invasive cancers (> or = 15 mm), and 42% more small invasive cancers (< 15 mm) than programmes using one view mammography.
The success of the screening programme depends largely on the ability of individual programmes to detect small invasive cancers. The results suggest that the benefit of using two view mammography is largely in the increased detection of these cancers.
比较双侧乳腺钼靶摄影与单侧乳腺钼靶摄影在检测小（<15毫米）浸润性癌方面的效果。
来自英国国家医疗服务体系乳腺筛查项目（NHSBSP）的筛查项目数据。
整理了英国所有筛查项目在1994年4月1日至1995年3月31日筛查年度的标准“科纳”报表（KC62表格）数据。将采用单侧和双侧乳腺钼靶摄影的项目的浸润性癌检出率与间接年龄标准化浸润性癌检出率进行比较。
在NHSBSP中，对参加普查（首次筛查）的女性采用双侧乳腺钼靶摄影的项目，与采用单侧乳腺钼靶摄影的项目相比，检测出的非浸润性/微浸润性癌多3%，大浸润性癌（≥15毫米）多7%，小浸润性癌（<15毫米）多42%。
筛查项目的成功很大程度上取决于各个项目检测小浸润性癌的能力。结果表明，采用双侧乳腺钼靶摄影的益处主要在于这些癌症检出率的提高。
