Proton therapy for children: the procedure

The treatment step by step

As it is important that children lie perfectly still during the treatment, it may be necessary to put them to sleep for a while.

Read all about the procedure of the treatment with or without anaesthesia.

From Radio-Robbie to the Chain of Courage

Special attention is paid to the youngest patients. For example, Radio-Robbie, the Chain of Courage and a specially designed Lego set bring the subject of cancer into children's lives.


Radio-Robbie is a superhero who fights bad cancer cells with his friends.

The Radio-Robbie booklet explains in simple terms and with the help of drawings what cancer is, what happens when you get radiotherapy and why - for example - it makes you so tired. The children also receive a Radio-Robbie doll and a personalised Radio-Robbie cape.

Chain of Courage

The Chain of Courage is a source of support during therapy. For a particular treatment, examination or event, the child receives a bead for their necklace.

Lego set

To familiarise the children with what will happen, the hospital developed a Lego building kit. Step for step, the children can build the proton therapy device, the treatment room and the various facets of their radiotherapy. It is also a fun and accessible way to explain to friends or teachers at school what will happen to them at the hospital.

Electric cars

There are also electric cars that the children can use once a week to drive from the waiting area to the treatment area.

Ring the bell

At the end of the treatment series the children are allowed to ring the bell, marking the closing moment of their proton therapy treatment.

The social worker can also give you information about fun, child-friendly trips in the area.
