When prostate cancer spreads to other parts of the body, bone is almost always the first place. Bone metastases will be painful for the patient and lead to other dangerous problems, such as fractures, spinal cord compression or high blood calcium, even life-threatening.

If prostate cancer has metastasized, bone is often the first place. Therefore, when cancer has spread beyond the prostate, the goal of treatment will be to prevent or slow metastasis to the bone. In case it has really metastasized to the bone, it is necessary to relieve pain and control other complications.
