The radiotherapy team plan your external beam radiotherapy before you start treatment. This means working out the dose of radiotherapy you need and exactly where you need it.
You might have radiotherapy to try to reduce symptoms of advanced ovarian cancer. You have it in the radiotherapy department at the hospital.
