Wear A Hat Day is one of the UK's biggest and most important brain tumour research fundraising and awareness-raising days. Wearing a hat or one of our specially designed hat-themed pin badges is a sign of support for Brain Tumour Research, our mission and all those living with, or lost to, a brain tumour.

Brain Tumour Research is uniquely focused on funding sustainable and long-term research into brain tumours at dedicated UK Research Centres. Your support will help us get closer to a cure for brain tumours. The Charity is building a network of brilliant researchers and developing the next generation of world-class experts in neuro-oncology. We're also influencing the Government and larger cancer charities to invest more nationally into this crucial area of medical research.
