Does radiotherapy treat bone cancer?

Radiotherapy uses carefully planned radiation to damage cancer cells in a chosen area. For a primary bone tumour, surgery is often considered when the tumour can be removed, while radiotherapy may be discussed when surgery is not suitable, when cancer cells may remain locally, or when the tumour needs local control.

Radiation can also be used when bone cancer has spread to another bone. In that setting, treatment may reduce pain, protect movement, or help manage pressure from a growing tumour. The plan depends on the bone involved, the tumour type, nearby organs and whether other treatments are needed.

Ask the oncology team why radiotherapy is being considered and what outcome they expect from it. Planning may include scans, marking the treatment area and a discussion of how to protect nearby healthy tissue.

Tell the team about pain, weakness, reduced movement, previous radiation, medicines and any metal implants. Do not stop prescribed treatment because of a new symptom; report it so the plan can be adjusted safely.

Contact the treating team promptly if bone pain changes quickly, a limb becomes weaker, or movement suddenly becomes difficult. Seek urgent medical help for new loss of bladder or bowel control, numbness around the groin, or severe back pain with leg weakness, because these can signal pressure on the spine.

Which bone is being treated, and is the aim tumour control, symptom relief, or both? What alternatives or additional treatments are relevant? How might treatment affect strength, movement and the nearby skin or organs?
