Does palliative radiotherapy treat cancer pain?

Radiation is aimed at a specific painful tumour or metastatic site. By reducing tumour activity and local inflammation, it may lessen pressure or irritation around nerves, bone or other tissues. It is one part of a pain plan and does not replace prescribed pain medicine unless your clinician changes it. The response varies with the pain’s cause and location. Some people notice a temporary increase in discomfort before improvement, so ask how to manage that possibility.

Describe the pain’s location, character, severity, timing and effect on sleep, movement or eating. Bring a list of medicines, including doses and medicines used only when needed. Your team may use examination and scans to decide whether a local target is present and whether radiotherapy, medication, a procedure or a combination fits your needs. Take pain medicines as prescribed and record changes rather than waiting until pain becomes difficult to control.

Seek urgent help for pain that suddenly becomes severe, new weakness or numbness, trouble walking, loss of bladder or bowel control, confusion, or pain with a suspected fracture. Call your cancer team promptly when prescribed medicine no longer controls the pain, causes troublesome sleepiness, or produces repeated vomiting. These changes may require assessment rather than simply increasing a dose yourself.

Ask what is causing the pain, whether there is a treatable radiation target, when relief may begin, and which medicines to continue. Ask about side effects, safe activity, and the contact route for pain that worsens after treatment.
