ACR accredited suburban mammography center. Three year results

The results of patients recommended for biopsies were reviewed retrospectively as well as the prevalence and incidence of breast cancer detected during a three-year course, October 1984-October 1987, in an American College of Radiology accredited mammography imaging center. The prevalence of cancer was 26.11 per thousand in 2,681 symptomatic patients and 21.13 per thousand in 1,162 asymptomatic patients. The average annual incidence was 1.9 per thousand women years. The ratio of cancer to benign biopsies was 1:2.13. This is a reasonable and cost-effective result for this free-standing center during the time interval evaluated. To date: sensitivity, asymptomatic .82, symptomatic .96; PPV, asymptomatic .21, symptomatic .42; specificity, asymptomatic 92, symptomatic 96.
