The idea of making brain cancers glow to help surgeons operate is being tested in the UK.  Patients will be given a drug, 5-amino-levulinic acid (5-ALA), which causes a build-up of fluorescent chemicals in the tumour.  The theory is that the pink glow will clearly mark the edges of the tumour, making it easier to ensure all of it is removed.
