Brain tumour research

This study will investigate how brain and skull-based tumours develop and progress.  It is looking for people who have not had a brain tumour or neurological condition to act as ‘control participants’.

Results of this study will be used to inform the development of new tests to help diagnose brain and skull-based tumours, as well as new treatments and care for the future.

It is being carried out by a team of researchers from The University of Manchester, the Geoffrey Jefferson Brain Research Centre, and Salford Royal Hospital (part of the Northern Care Alliance NHS Foundation Trust).
