How long can bone metastasis live depends on the type of primary tumor and the treatment measures taken, and cannot be generalized. Bone metastasis is a malignant tumor that originates outside of bone tissue and can metastasize to bone tissue via bloodstream, causing bone damage, pain and other manifestations. In general, the life expectancy after bone metastasis mainly depends on whether the patient can undergo aggressive treatment at the time of bone metastasis and the origin of the primary tumor. Most patients are in advanced stage once bone metastasis occurs, and the 5-year survival rate of advanced malignant tumors is within 10%. However, with the advent of targeted drugs and immunotherapy, the 5-year survival rate of some tumors can reach about 20%-30% even if bone metastasis occurs. Therefore, it is suggested that patients should go to oncology department for consultation and treatment in time after bone metastasis occurs, and they can be given radiotherapy, chemotherapy, surgical palliative surgery and other treatments, and can also consider Chinese medicine treatment.
