Cancer influence on the skeleton results in two main negative consequences: pain and Skeletal-Related events (sre), defined as any of the following:

• pathologic fracture,
• a requirement for surgical intervention and palliative radiotherapy to bone lesions,
• spinal cord compression,
• hypercalcemia of malignancy.

Many disciplines should be involved in the management of breast cancer bone metastases, including medical oncologists, radiation oncologists, palliative care specialists, Treatment of bone metastases ideally involves a multidisciplinary team, including medical oncologists, palliative care specialists, radiation oncologists and orthopedic surgeons.
