Itisanobrainer aims to raise awareness of brain tumours, which are currently the biggest cancer killer of children and young people. Supporters take a picture with a Brain Tumour Charity bandana, which then gets changed to the black and white images you see on the site.

We wish to change the outcome for families with this disease and can only do this if the word spreads – the idea is a “no brainer’! Follow us on twitter @itisanobrainer.
