Radiotherapy for pain relief is treatment given to reduce symptoms caused by cancer. It is often called palliative radiotherapy.
This does not mean your team has given up on you. It means the goal of this treatment is relief: less pain, less bleeding, less pressure, or better function.
Common Indications for Radiotherapy for Pain Relief
Your doctor may recommend it for:
- Bone pain from cancer spread.
- Painful spine deposits.
- Bleeding from a tumour.
- Pressure on nerves.
- Pain from a tumour pressing on organs.
- Symptoms from brain or lung cancer spread.
What exactly does this treatment do?
It can shrink or calm the tumour in the treated area. This may reduce pain, bleeding, pressure, or swelling.
How should I prepare?
You may still need a planning scan, even if the treatment course is short. Bring your pain medicines and tell the team which positions make your pain worse.
Do I need to stop taking medication?
No, not unless your doctor says so. Keep taking your pain medicine as prescribed. Radiotherapy may take time to work, so do not stop pain relief too early.
What happens when I arrive?
The radiotherapy team positions you on the treatment couch. They know many people coming for pain relief are already uncomfortable, so tell them where you need support.
How is the treatment performed?
The machine gives radiation to the painful or troublesome area. It does not touch you and the radiation itself is painless.
How long does treatment take?
Some people have one session. Others have a short course over a few days. Your doctor chooses based on your symptoms and general condition.
When will the pain improve?
Pain relief is not always immediate. Some people feel better within days, while others improve over a few weeks. Pain can briefly flare before it settles.
When should I seek urgent help?
Seek urgent assessment for new leg or arm weakness, numbness, loss of bladder or bowel control, sudden severe back pain, confusion, or a suspected broken bone. These symptoms may need treatment before radiotherapy has time to work.
Are there risks?
Side effects depend on the treated area. You may feel tired or sore, and treatment near the bowel, bladder, throat, or skin can cause local symptoms.
Can children have this treatment?
Yes, in selected cases. Children need specialist planning and a team experienced in paediatric cancer care.
Can I have this treatment if I am pregnant?
Pregnancy Precaution
Tell your doctor or radiotherapy team if you are pregnant or think you might be. Radiotherapy for symptom relief still uses radiation, so pregnancy must be discussed first.
Conclusion
Radiotherapy for pain relief is about making daily life easier. Keep taking your usual pain medicine until your doctor reviews it, and tell the team if your pain suddenly worsens.
