Before you start your treatment it needs to be planned. Planning makes sure that the radiotherapy is aimed precisely at the cancer so that it causes the least possible damage to the surrounding healthy tissue. All radiotherapy treatments are planned on an individual basis by your clinical oncologist, a physicist and sometimes by a senior or specialist radiographer.
Your first planning visit will take 30–60 minutes. The staff in the radiotherapy department will explain what to expect. It‘s important for you to feel that you’re involved in your treatment, so feel free to ask as many questions as you need to.
You’ll usually have a CT (computerised tomography) scan taken of the area to be treated. You may have some marks drawn on your skin to help the radiographer to position you accurately and set where the treatment will be delivered. It’s important not to rub them off until your treatment is finished. Sometimes tiny, permanent marks are made on the skin. At the beginning of your radiotherapy you’ll be given instructions on how to look after your skin.
