New light on Down's cancer link

Wednesday, 20 May 2009

Scientists may have solved the mystery of why people with Down's syndrome seem to have a lower risk of some cancers.

The extra copy of chromosome 21 which causes Down's appears to contain a gene that protects from solid cancerous tumours, tests on mice suggest.

The gene seems to interfere with signals a tumour relies on to grow. The finding raises hope of new ways to prevent and treat cancer.

The study by the Children's Hospital of Boston appears in the journal Nature. the rest image
