Preparing for your treatment

When you arrive for your pre-treatment appointment, the radiographers will explain to you what will happen. Please ask if you don’t understand anything.

You will usually be asked to undress depending on which part of your body is to be treated. Gowns will be provided and every effort will be made to maintain your dignity and privacy.

You will be positioned on the pre-treatment couch and asked to lie very still. The position will be the same as the one you will lie in for your treatment. If you have recently had surgery, for example to the breast, it is not always easy to get into the position. You may find it helpful to practise getting into this position before your treatment starts. The CT scanner or simulator will move around and you may hear all sorts of unfamiliar sounds. The lights in the room will be switched off and on during planning.

Marks on your body


The treatment areas will be defined and marked out on your body using one or more small permanent reference marks (tattoos) about the size of a pinhead of coloured, permanent ink. These provide a reference point during radiotherapy. You will be asked to consent to the use of tattoos.

As these tattoos are made with dark ink, they may not show so easily on black skin. If this is a concern for you, ask your radiographer if there are any alternative options.

Sometimes an indelible pen may be used to mark out the field, although this option is not always available. If this happens, you will be asked not to remove these marks until the end of treatment.

Depending on which part of your body is going to be treated, it can be helpful to think about the clothing you wear to this appointment. You may wish to make sure that you wear clothes that cover up any marks.

If you are to have treatment to your head or neck, any marks will be made on your shell.

Changes to the treatment plan


Sometimes changes will be made to the treatment plan, for example the size of the treatment field may be reduced. These changes can usually be made on the treatment machine. A change in the plan is quite usual and doesn’t mean that anything has gone wrong.

Comparing treatments


It’s natural for you to compare your treatment with other people who have the same condition but remember - your radiotherapy is planned individually for you. Each person’s plan will be different including which radiotherapy machine is used and how many treatments you receive.
