Secondary bone cancer. Coloured frontal (left) and sagittal (right) positron eletron tomography (PET) scans of a patient with secondary bone cancer (yellow). The cancer has spread (metastasised) from a primitive lung cancer (primary cancer) that cannot yet be detected on the scan. The cancerous cells in the bone will resemble those from the lung. Treatment of secondary bone cancers usually involves a combination of radiotherapy and chemotherapy but depends on the type of primary cancer. Bone strengthing drugs (bisphosphonates) are also used to reduce the risk of fracture.
