Over 4,000 people are diagnosed with new cases of brain or central nervous system (CNS) cancer every year in the UK. Glioblastomas are the most common and aggressive form of brain tumour in adults. Research at the Cambridge Cancer Centre is focused on understanding the different types of brain tumours that develop in both adults and children, finding the most effective ways of diagnosing brain tumours as early as possible, developing new treatments, and monitoring how tumours are responding to treatment.
