How much more time does a person have if bone cancer?

Not feasible to : Answer. The survival time depends on many factors, like the type of tumor, stage of tumor, response to therapy, general health of the patient and vagaries of tumor biology.

Could be Years: As dr. Singh explained, there are too many variables that are unknown in order to answer this question. However, if the bone is the only site of spread and if the cancer is sensitive to chemotherapy, one can almost consider bony metastasis as a chronic illness--controllable but not curable--with which one may live for years.
