How long can bone cancer live in the late stage is related to the type of bone cancer, treatment measures and so on, and needs to be analyzed on a case-by-case basis. Bone cancer is divided into primary bone cancer and secondary bone cancer. Primary bone cancer refers to bone sarcoma, which is highly malignant and can have multiple metastases in late stage, and patients may have obvious pain, functional impairment and other symptoms, and the survival time is shorter, which may be about one year. The late survival time of secondary bone cancer patients needs to depend on the condition of the primary lesion, treatment measures, underlying disease condition, etc., and cannot be generalized. The average survival time may only range from half a year to one year, which is basically incurable and can only prolong the survival period as much as possible. For patients with advanced bone cancer, palliative treatment is the main treatment. For patients with pain symptoms, they can take oral pain medication according to medical prescription to improve their quality of life.
