Treatment mask

A mask that is made specifically to fit your head, that is attached to the treatment table and holds your head in position during radiotherapy treatment. This is important, as you need to stay very still during the treatment, so that the radiotherapy is directed to the correct part of the brain i.e. the tumour. The mask may be made of plastic or Plaster of Paris, and is moulded to the shape of your head.
