Mammography is the most important method for the diagnosis and the screening of breast diseases. Sensitivity and accuracy of mammography are very high in the detection of breast cancer. The use of the stereotaxic localization and fine-needle aspiration of nonpalpable breast lesions improve its effectiveness. The American Breast Cancer Detection Demonstration Project (BCDDP) has demonstrated the benefits of breast screening for women over 40 years of age. Many American medical associations and societies have adopted the guidelines based on the BCDDP results, promoting breast cancer screening for these women. However, recently released results of some randomized breast screening studies demonstrated only a 5% reduction in mortality from breast cancer in women 40-49 years of age, and a 40% reduction for women aged over 50 years. There is no explanation for this dilemma at the present time. However, screening mammography should stay available for women over 40 years of age.
乳房X线摄影是诊断和筛查乳腺疾病的最重要方法。乳房X线摄影在乳腺癌检测中的敏感性和准确性非常高。立体定位和对不可触及乳腺病变的细针穿刺活检的应用提高了其有效性。美国乳腺癌检测示范项目（BCDDP）已证明对40岁以上女性进行乳房筛查的益处。许多美国医学协会和学会已根据BCDDP的结果采用了相关指南，推动对这些女性进行乳腺癌筛查。然而，最近公布的一些随机乳房筛查研究结果显示，40 - 49岁女性的乳腺癌死亡率仅降低了5%，50岁以上女性降低了40%。目前对于这一困境尚无解释。然而，40岁以上女性仍应可进行乳房筛查。
