Genetic clue to brain cancer risk

Genetic warning signs of an increased risk of the commonest kind of brain cancer have been discovered.

UK and US scientists identified genetic indicators that someone is at greater risk of developing a glioma - which accounts for 50% of all brain tumours.

However, the teams from London, Texas and California write in Nature Genetics that environmental factors also affect if someone will develop the cancer.

A UK charity said the work opened up new avenues for research and treatment
