The incidence of invasive breast cancer among women aged > or = 65 years is twice that among those aged 35-44 years (1), and the death rate from breast cancer is approximately three times higher among women aged > or = 65 years than among women aged 35-64 years (2). Although routine screening mammography among women aged > or = 50 years can reduce breast cancer mortality by > or = 30% by detecting tumors at early, more treatable stages (3), older women are less likely to receive screening mammograms (4). The Health Care Financing Administration (HCFA) routinely examines trends in the use of health services by age, race, and sex to monitor access to medical care for Medicare beneficiaries. Using Medicare claims data, HCFA estimated rates of mammography use among women aged > or = 65 years during 1991-1993. This report presents the findings of this analysis.
65岁及以上女性浸润性乳腺癌的发病率是35 - 44岁女性的两倍（1），65岁及以上女性的乳腺癌死亡率比35 - 64岁女性高出约三倍（2）。尽管50岁及以上女性进行常规乳腺钼靶筛查可通过在早期更易治疗阶段检测肿瘤使乳腺癌死亡率降低30%及以上（3），但老年女性接受乳腺钼靶筛查的可能性较小（4）。医疗保健财务管理局（HCFA）定期按年龄、种族和性别检查医疗服务使用趋势，以监测医疗保险受益人的医疗服务可及性。HCFA利用医疗保险理赔数据估算了1991 - 1993年期间65岁及以上女性的乳腺钼靶检查使用率。本报告展示了该分析的结果。
