Scientists unveil extensive child cancer research data

US scientists have released the world's largest collection of genetic data on childhood cancers in a bid to speed up treatment discoveries.

The US Pediatric Cancer Genome Project has mapped the entire genome - all the DNA - of 260 young cancer patients.

By finding differences between each youngster's normal and cancerous cells, scientists have pinpointed causes of some of the most deadly child cancers.

They hope by sharing their work others will be able to make new breakthroughs.
