Treating bone cancer. Treatment for bone cancer depends on the type of bone cancer you have, how far it has spread and your general health. The main treatments are surgery, chemotherapy and radiotherapy.
When people have cancer in bones, often it is cancer that has spread there from elsewhere in the body. This is metastatic cancer. Even though it spreads to bone, it is not considered bone cancer because the tumor cells are from the primary cancer. For example, a person with lung cancer that has spread to the bone is considered to have lung cancer with metastasis to the bone -- not lung cancer and bone cancer.
