Stage 1 Breast Cancer and Bone Mass in Older Women

摘要

The specific aims of the study are (1) to assess the bone mineral density of women 65 years of age and older with breast cancer in comparison with the bone mineral density of same aged women with normal mammograms; (2) to examine the risk factors associated with breast cancer and low bone mass in these two groups of women; (3) to develop a model based on the study population to determine -the predictive value of low bone mass for risk of breast cancer. During the three years of this study, a total of 300 women (cases with breast cancer and controls with a normal mammogram) aged 65 and older will be recruited from oncology and radiology offices to participate in a study consisting of one clinic visit.
