A questionnaire survey of consultant surgeons in England was undertaken to establish the preferred surgical management of early breast cancer. The Regional Health Authority in which each surgeon worked was recorded to document regional variation. The 14 Regional Health Authorities were divided into three geographical areas: north, central and south. The main finding was that proportionately more surgeons in the north would recommend mastectomy (P < 0.0001) rather than conservative surgery compared with those in the central and southern areas. The nature of the study does not allow explanations for such variation.
对英国的外科顾问医生进行了问卷调查，以确定早期乳腺癌首选的手术治疗方式。记录了每位外科医生所在的地区卫生管理局，以记录地区差异。14个地区卫生管理局被划分为三个地理区域：北部、中部和南部。主要发现是，与中部和南部地区相比，北部地区有更多比例的外科医生会推荐乳房切除术（P<0.0001）而非保守手术。该研究的性质不允许对这种差异作出解释。
