Planning external radiotherapy
Your radiotherapy treatment plan is individual to you.
You have a planning scan that will be used to create your radiotherapy plan. The planning scan is usually a CT or MRI scan. The radiotherapy team then works out the dose of radiotherapy you need and exactly where you need it.
You might have to wait a few days or up to 3 weeks before you start treatment.
