Researchers develop genetic test that diagnoses brain tumours in hours

Scientists in Nottingham and at Mass General Brigham have developed a brain tumour test that gives results in just two hours. Previously, patients waited six to eight weeks for a diagnosis.

The test looks for genetic mutations linked to brain cancer. It uses fluid taken from the spine or collected during surgery, so doctors do not always need to remove tissue directly from the brain.

Surgeons can receive the results while an operation is still happening. This means they can make better decisions about treatment straight away.
