Many women on aromatase inhibitors are also prescribed bone-strengthening medications like bisphosphonates, said Lillie Shockney, administrative director at Johns Hopkins Breast Clinical Programs. But recent findings suggest that even bisphosphonates can raise a woman's risk of femur fractures.
"It is important for the primary care doctor and the medical oncologist to discuss this before automatically doing so (prescribing bisphosphonates), as these bone-building agents are not side-effect free either," said Shockney.
Most importantly, the way to prevent bone loss is simple: women need to stay active.
"Brisk walking several times a day or hopping on a treadmill is an effective way to keep bones strong," said Shockney. "Bone density should be reassessed periodically while on hormonal therapy and beyond."
