Finger-prick test could help spot brain cancer recurrence sooner

Researchers designing lateral flow test that patients could use at home and avoid six-month wait for MRI scan

Scientists are developing the world's first finger-prick test to spot brain tumours. More than 300,000 people worldwide are diagnosed with brain cancer each year, and while treatments have improved over the last few decades, recurrence remains a risk.

The unpredictable timing of tumours coming back makes them difficult to detect early. Researchers are designing a lateral flow test to pick up signs of recurrence that could be used by patients at home.
