Radiotherapy uses high-energy rays to destroy cancer cells. This treatment aims to treat cancer or relieve symptoms.
Radiotherapy uses carefully calculated doses of radiation to treat cancer as well as some non-malignant conditions.
It is painless and only takes a few minutes to deliver.
Radiotherapy can be used alone or with surgery, chemotherapy, or both.
It’s used to:
- Attempt to cure cancer (radical radiotherapy)
- Control/slow down the growth of cancer
- Relieve cancer symptoms (palliative radiotherapy)
The type of radiotherapy you’re given will depend on the type of cancer you have and your individual situation:
- External Beam – delivers radiation from outside the body using a Linear Accelerator (Linac)
- Internal Radiotherapy – Brachytherapy delivers radiation to body cavities or tissues internally using a specialist machine. For more information see our page on Brachytherapy.
