Our son Oliver was diagnosed with a brain tumour 4 years ago.  His experience made us aware of how limited the treatment options are for this devastating cancer.  We will be doing the Twilight Walk in London during Brain Tumour Awareness Month to raise funds for the Brain Cancer Trust.  They are supporting research aimed at understanding the condition and accelerating a cure.  Brain tumours are the biggest cancer killer of children and adults under the age of 40. The Brain Cancer Trust believes that fighting brain tumours on all fronts of research, awareness and support is the only way to save lives, reduce long-term disabilities and to help everyone affected by a brain tumour. They need your help because a cure can't wait.
