Wear A Hat Day takes place on Friday 31st March. Join in, look super for science and help research breakthroughs happen. Brain tumours kill more children and adults under the age of 40 than any other cancer, yet historically just 1% of the national spend on cancer research has been allocated to this devastating disease. Brain Tumour Research is determined to change this. Getting involved in Wear A Hat Day will help the charity get closer to its vision of finding a cure for all types of brain tumours. Funds and awareness raised support the charitys vital campaigning to increase the national investment in brain tumour research, as well as sustaining the pioneering research being undertaken at Brain Tumour Research Centres of Excellence where scientists are working tirelessly to find a cure for all types of brain tumours.
