Purpose: To test whether bisphosphonates for osteoporosis reduce the risk of breast cancer.Background: Observational studies and meta-analyses find that women taking bisphosphonates have about a 1/3rd reduction in risk of breast cancer as soon as 1 year of treatment. This is plausible because bisphosphonates have in vitro anti-tumor activity and high doses of zoledronate reduce recurrence in women with breast cancer. However, observational studi...

Previous studies found a negative correlation between vertebral bone marrow fat (MF) and bone density (BMD). Proposed mechanisms for this include i) a shift in stem cell lineage allocation from osteoblasts towards adipocytes, and ii) an increase in osteoclast-promoting cytokines with greater MF. However, little is known about the relationship between MF and bone markers. To assess these relationships in older adults, we used data from the AGES-Reykjavik cohort. MF was measured...
