between BAC and systemic disorders such as cardiovascular disease, diabetes mellitus and hypertension. The aim of this study was to determine the association between reduced bone mineral density and BAC. The study population consisted of 567 women who had both mammography and bone mineral density evaluation. BAC [+] and BAC [-] women were compared for age, body mass index, postmenopausal duration, number of deliveries, breastfeeding duration, DM, HT, lipid treatment, osteopenia, and osteoporosis. BAC was seen in mammographic evaluation of 179 women and 388 subjects without BAC accepted as the control group. There was a statistically significant relationship between age, postmenopausal duration, number of deliveries, history of DM, HT, lipid treatment and BAC. While the prevalence of osteopenia was higher in control group [52.8%] , the rate of osteoporosis [48.7%] was higher in group with BAC. There was statistically significant relationship between BAC and osteoporosis in postmenopausal women. Determination of BAC in routine screening mammography might be helpful in both identifying women with risk of cardiovascular disease and osteoporosis
