What to expect from radiotherapy for bone cancer

Radiotherapy directs energy at a defined area of bone or nearby tissue. It may be chosen to treat a primary bone tumour, reduce pain from cancer affecting bone, or help control symptoms that threaten movement. Scans and examination guide the area, dose, and schedule.

You remain still during each session, often with supports or moulds to make positioning repeatable. The beam is not felt and does not make you radioactive. Pain may improve gradually rather than immediately, and some people experience a short-lived pain flare before improvement.

Tell the team where pain limits walking, sleep, or daily tasks, and report all pain medicines and supplements. Use walking aids exactly as advised and avoid movements that cause sudden or worsening pain. Keep the treated skin clean and dry; ask before applying creams or using heat over it.

Plan rest around appointments, but maintain gentle movement within your safe limits. Fluids, regular meals, and support with transport can make treatment days easier. Keep follow-up visits so your team can assess pain, mobility, strength, and the need for other treatments.

Seek urgent medical advice for sudden severe bone pain, a new inability to stand or walk, new weakness or numbness, loss of bladder or bowel control, or pain after a minor movement. These symptoms can indicate a fracture or pressure on nerves and need rapid assessment.

Ask what the treatment is intended to achieve, when pain relief may begin, how to protect a weakened bone, which activities are safe, what pain flare plan to use, and which symptoms require an emergency assessment.
