A recent development that enables tumours to glow in the dark holds promise in the treatment of malignant brain tumours.
A trial is on in the UK for patients newly diagnosed with glioblastoma.
As a part of the trial, more than 60 patients will receive injections of 5-amino-levulinic acid (5-ALA), which will be converted into a fluorescent chemical in the tumour. The tumor will then glow when placed under a UV light.
This fluorescent colour of the tumor helps surgeons clearly view the edges of the tumor, so that the tumor can be removed completely from the brain.
