A more recent British trial, performed on women aged 39-41, used only mammography, as did the largest of all, the Swedish two-county trial. Though the trial results have been inconsistent, the conclusion is clear: breast-cancer screening does not reduce mortality rates.
欧洲的英国在20世纪70年代进行过一次试验，筛查组同样采用X光乳腺造影和乳房检查。近期一次英国试验针对39-41岁的女性，和规模最大的瑞典两县试验一样只采用X光乳腺造影检查。虽然试验结果略有出入，但结论却十分明确：乳腺癌筛查并不能降低死亡率。
