At present, there is no authoritative data indicating how long lung cancer bone metastasis can live. Generally speaking, the median survival time of patients with lung cancer bone metastasis is 6~10 months, but due to the existence of individual variability, it is impossible to make a generalization. Lung cancer bone metastasis refers to the secondary damage of bone caused by the hematogenous transfer of lung malignant tumor cells to bone tissues, which belongs to the important sign that lung cancer enters into advanced stage. Generally speaking, the survival time of patients with lung cancer bone metastasis is 6~10 months, and there are differences in patients’ conditions and individual physique. Some patients can prolong the survival time and improve the quality of survival after active treatment, and the 1-year survival rate reaches 40%, which cannot be generalized. When patients can develop complications such as pathological fracture and hypercalcemia, the survival period may be further shortened. Once patients develop bone metastasis of lung cancer, they need to go to regular hospitals and take relevant treatment measures under doctors’ guidance to avoid delaying the condition. In daily life, patients need to rest in bed and protect the pressure surface to avoid bedsores.
