How long can bone metastases live in general requires specific analysis and cannot be generalized. The survival period of bone metastases is related to the type of primary tumor and the progress of disease, whether there are combined organ metastases, whether there are single or multiple bone metastases, and whether the patient is sensitive to radiotherapy, endocrine and other treatments. In general, patients with prostate cancer and breast cancer who have bone metastases have a relatively long survival period, such as 3-5 years; if they are treated reasonably, they can achieve a longer survival period. The prognosis of patients with bone metastases from kidney cancer and thyroid cancer is also better and the survival period is more objective. However, if patients with lung cancer and liver cancer have bone metastases, the prognosis is relatively poor, and the survival period is about 0.5-1 year. However, with the introduction and application of targeted drugs, the survival period of patients can also be extended. In addition, patients should avoid strenuous activities and excessive load in daily life, prevent falls and bruises, and give high-calorie, high-protein, vitamin-rich and easy-to-digest diet to improve the immunity of the body.
