Breast cancer (BCa) is a malignant disease which preferentially metastasizes to the bone. 1,2 The consequences of this complication, which occurs in ~70% of metastatic BCa patients, may result in skeletal-related events (SREs) which encompass debilitating pain, impaired mobility, hypercalcaemia, pathologic fractures, spinal cord or nerve root compression, and bone marrow infiltration. 2,3 These pathological conditions negatively affect the performance status, quality of life (QoL) and survival of these patients. 3,4 The clinical treatment of bone metastasis from breast cancer is essentially aimed at palliating pain, maintaining function and preventing SREs. 3,4 This treatment requires a multidisciplinary approach, which is costly to the health care system. 4,5 On the other hand, although the current therapeutic options, based on the systemic administration of antiresorptive agents, 6 radiopharmaceuticals 7 or local treatment such as radiation therapy, 8 radiofrequency ablation 9 or surgery, 10 are effective in decreasing the tumour burden and slowing bone metastasis by reducing the extent of bone destruction, they are
