在1987- 1994年期间，在芬兰图尔库市进行的一项基于人群的乳房X线摄影筛查中，对36 000名40-74岁妇女进行了129 731次检查。50岁以上的妇女每隔2年进行一次筛查，50岁以下的妇女每隔1年或3年进行一次筛查，这取决于她们的出生年份。筛查发现的乳腺癌有385例，在同一时期，同一城市同一年龄组的154名妇女在筛查之外被诊断患有乳腺癌，并发现了100例间隔期癌症。250例（67%）筛查发现的癌症为手术后I期，而45例（45%）为间隔期癌症，52例（34%）为筛查外发现的癌症（P
In a population-based mammography screening, 129 731 examinations were carried out among 36 000 women aged 40-74 in the city of Turku, Finland, in the period 1987-94. Women older than 50 were screened at 2-year intervals, and those younger than 50 at either 1-year or 3-year intervals, depending on their year of birth. Screen-detected breast cancers numbered 385 and, during the same time period, 154 women were diagnosed with breast cancer outside screening in the same age group in the same city, and 100 interval cancers were detected. Two hundred and fifty (67%) of the screen-detected cancers were of post-surgical stage I compared with 45 (45%) of the interval cancers and 52 (34%) of the cancers found outside screening (P
