Abstract: Breast cancer exhibits high risk to metastasize to bone.Skeletal-related events caused by bone metastases can significantly affect the quality of life and outcomes of patients with breast cancer.Therefore, such events play an important role in clinical staging and treatment protocols for early and accurate diagnosis of bone metastasis in breast cancer and for improving patient prognosis.The review summarizes the research status of imaging examination of bone metastasis in breast cancer and provides evidence for early diagnosis of bone metastasis.
