Innovative Finger-Prick Test for Early Brain Cancer Detection
Every year, countless lives are deeply affected by brain tumours, with over 300,000 people around the world receiving a diagnosis, resulting in approximately 240,000 annual fatalities. Sadly, the lack of adequate tests for this devastating disease often means that aggressive tumours, when they reemerge, go undetected until it’s too late. Early detection could make a world of difference in reducing the tragic consequences of recurrent brain cancer, and there’s hope on the horizon.
A dedicated team at Nottingham Trent University (NTU) is hard at work on a groundbreaking project: the creation of the world’s first finger-prick test for detecting brain tumours. If successful, this innovation could potentially save thousands of lives globally. The research is generously supported by the Medical Research Council, with valuable contributions from researchers at the University of Sheffield.
This new test not only has the potential to transform healthcare outcomes but also promises to ease the strain on healthcare systems by reducing the demand for MRI scans and offering a cost-effective alternative to some clinic appointments.
But what exactly is a finger-prick device? These are simple tools that use a tiny needle to collect a drop of blood for testing, making it a convenient way to monitor various health aspects, like blood sugar levels in individuals with diabetes.

Brain Tumor Types
Now, let’s talk about brain tumours. These are abnormal masses of tissue where cells grow and multiply uncontrollably. There are two primary types: primary brain tumours, which originate in the brain tissue, and metastatic brain tumours, which can start in other parts of the body and migrate to the brain, typically through the bloodstream. There are over 150 different kinds of brain tumours.
According to the American Association of Neurological Surgeons, in 2019, there were 347,992 new cases of brain cancer documented worldwide, resulting in 246,253 deaths from brain cancer globally.
The significance of early detection cannot be overstated. As Professor Philippe Wilson, an expert in One Health at NTU, rightly points out, brain tumours are best managed when detected early. Unfortunately, recurrence is a significant challenge, with some tumours returning rapidly and aggressively. Waiting six months for an MRI scan can mean that a tumour has already had a considerable head start, which is why this finger-prick test is so crucial.

Global Lifesaving Technology
Imagine a medical technology as widely recognized and used as the lateral flow test, but applied to disease monitoring at home. This breakthrough has the potential to offer regular, affordable health monitoring for patients in a user-friendly way. The hope is that this technology can be adapted to other types of cancer, ultimately playing a role in saving countless lives around the world.
The researchers are currently focused on developing lateral flow tests that can detect specific molecules in the blood associated with brain tumours, providing early indications of their return. Prototypes are already in the works as part of the project, with plans to move on to clinical trials. This advancement in technology could make a significant impact in detecting aggressive and malignant forms of brain tumours, potentially offering a lifeline to those affected.
