Data on breast surgery from national samples of patients discharged from hospital in the United States and in England and Wales were reviewed for the years 1970-80. In the United States the rate of breast surgery increased dramatically in 1974 and 1975, but in Britain it remained constant and well below the level in the United States. In both countries the proportion of radical mastectomies declined and the proportion of less extensive procedures rose. The increase in mastectomy rates in the United States probably resulted from increased public concern about breast cancer and from the promotion of breast screening in the mid-1970s. The costs, morbidity, and early mortality associated with a higher rate of mastectomy are substantial and the advantages unclear.
对1970年至1980年间美国、英格兰和威尔士出院患者的全国样本中的乳房手术数据进行了回顾。在美国，乳房手术率在1974年和1975年急剧上升，但在英国则保持稳定且远低于美国的水平。在这两个国家，根治性乳房切除术的比例都有所下降，而范围较小的手术比例则有所上升。美国乳房切除术率的上升可能是由于公众对乳腺癌的关注度增加以及20世纪70年代中期乳房筛查的推广。较高的乳房切除术率所带来的成本、发病率和早期死亡率相当可观，而其优势尚不清楚。
