Screening is defined as identification of individuals within an asymptomatic population who have specified disease at a time when intervention may result in improvement of prognosis of the disease. Identification of the disease at the earlier phases of progression improves prognosis. All kinds of cancer screening may not have same benefit. Screening for breast cancer has been found to be beneficial. Randomized controlled trials and meta-analysis have shown that screening by mammography reduces breast cancer by 25% and can significantly reduce mortality from breast cancer. This article reviews methodology and bias, modalities, benefits, problems, results and current guidelines of breast cancer screening.
筛查的定义是在无症状人群中识别出患有特定疾病的个体，此时进行干预可能会改善疾病的预后。在疾病进展的早期阶段识别疾病可改善预后。并非所有类型的癌症筛查都有相同的益处。已发现乳腺癌筛查是有益的。随机对照试验和荟萃分析表明，通过乳房X线摄影进行筛查可使乳腺癌发病率降低25%，并能显著降低乳腺癌死亡率。本文综述了乳腺癌筛查的方法、偏倚、方式、益处、问题、结果及当前指南。
