The effect of bone cement in the treatment of bone metastases is relatively limited, targeting metastases or localized bone tumors, it can provide some inhibition, but it cannot address the root cause of the tumor. Bone cement is a surgical material used to fill the defective part of the bone. Most of the metastatic tumors are the tumor cells transferring from other locations of the body to the bones by the medium of blood circulation, thus causing localized bone tumors, i.e., the appearance of bone metastasis. Bone cement treatment of bone metastasis is usually a local injection of bone cement, which kills tumor cells by diffusing in the body and uses the nature of coagulation to block the survival of tumor cells, serving the purpose of inhibiting tumor cells. But after all, it is only a local injection treatment, which can relieve the pain symptoms brought by bone metastasis to a certain extent. It is recommended that patients with bone metastases take the appropriate treatment under the assessment of the doctor to promote the recovery of the condition.
