Scientists have discovered a chemical that makes brain tumours glow pink and thus will help surgeons to remove the cancer safely.
In a trial scientists gave people glioma-a drink containing 5-ALA which is known to accumulate in fast-growing cancer cells.
The pink glow caused by the chemical was found in people with the most aggressive cancers.
Researchers hope it will make it easier for surgeons to distinguish between cancer cells and healthy brain tissue.
The National Institute for Health and Clinical Excellence approved the use of 5-ALA for patients with brain tumours, prior to surgery.
