Key breast cancer 'driver' gene found
- Cancer experts have identified a gene which can cause a particularly aggressive form of breast cancer to develop.
ZNF703 is the first "oncogene" to be discovered in five years.
It is overactive in around one in 12 breast cancers, and could account for up to 4,000 UK cases a year.
Cancer Research UK, whose scientists carried out the work, said the gene was a "prime candidate" for the development of new breast cancer drugs.
