  schema:description "Tumours in the lung, liver and upper abdomen move as you breathe. At the planning scan the team usually records the whole breathing cycle (4D CT) to see how far the tumour moves. They then plan to cover that movement, or reduce it by asking you to hold your breath, pressing gently on your tummy, or switching the beam on only at one point in each breath. They practise the breathing with you first."@en ;
