The survival time of patients with bone metastases from breast cancer cannot be specified, and is mainly related to the patient’s treatment and the development of the disease. Generally speaking, if the breast cancer has been treated surgically and the breast area has been removed, simple bone metastasis will not affect the patient’s life expectancy, but the discomfort caused by bone metastasis can affect the patient’s quality of life and can also cause pathological fractures. Of course, if the patient does not undergo surgical treatment or also has metastases from other sites, such as lung metastases or liver metastases, the patient’s survival will be greatly affected. Generally speaking, if the patient is not treated effectively in time to control further progress, usually the patient’s life expectancy will not exceed 3-4 years, or even shorter. Therefore, how long a patient with bone metastasis from breast cancer can live needs to be judged in the context of the specific disease. When patients have bone metastases, they can be treated with pain relief according to their individual condition, and then combined with chemotherapy and targeted therapy to prolong their survival.
