Bone health and breast cancer are two connected subjects, because breast cancer patients have a higher prevalence of osteopenia/osteoporosis and reduced bone health parameters than healthy woman of the same age. Therefore, the positive effect of adjuvant bisphosphonate therapy plays an important role in breast cancer treatment. Several randomized trials have studied bisphosphonates in the adjuvant setting in postmenopausal woman and demonstrated their potential to prevent treatment-induced bone loss. The prevention of fractures and the subsequent preservation of patients' quality of life are important arguments for the use of adjuvant bisphosphonates in postmenopausal breast cancer patients. In addition, trials of adjuvant bone-targeted agents showed a reduction of recurrences in and outside bone and an improved outcome in patients treated with bisphosphonates.
