Radiotherapy
What radiotherapy is, how it is planned and what you can ask your care team before treatment begins.
What it is
Radiotherapy uses high doses of radiation to destroy cancer cells or slow their growth. Depending on the situation, it can be used to treat cancer or relieve symptoms.
External beam radiotherapy
A machine aims radiation at the area of the body that needs treatment.
Brachytherapy
A radiation source is placed in or close to the tumour area.
Before treatment
For external beam radiotherapy, the team often uses a CT scan to plan the treatment accurately. Depending on the area, you may need a support or mould to help you stay in the same position at each session. Ask whether you need to prepare in a particular way for your appointment.
During treatment
Your individual treatment plan sets the number and timing of sessions. Possible side effects depend on the kind of treatment and the area treated. Ask your team what to expect and when to contact them.
What to ask
- What is the aim of radiotherapy in my case?
- How many sessions are planned and how should I prepare for them?
- What side effects might I notice, and whom should I contact if they occur?
