Increased breast calcifications in women with ESRD on dialysis: implications for breast cancer screening.

Background: Different appearances of breast calcification on mammography can differentiate benign from malignant disease. An increased incidence of breast calcifications in dialysis patients is established, but data for morphological characteristics in renal patients, incidence of benign and malignant calcifications, and clinical consequences are limited. In this study, we compare mammograms and the workup of abnormal calcifications of women on hemodialysis with that of women with normal renal function.
