Bad gene responsible for half of breast cancers?

October 5, 2009 Scientists say this discovery is one of the most important that's been made in the past 30 years.

The gene is called NRG1 and it's link was found by the University of Cambridge. It's thought to help suppress the growth cancer and is located on chromosome eight.

Everyone is born with an intact NRG1, but it seems that in some cases it can become damaged, allowing cancer to thrive.

Experts are hailing the findings published in the journal Oncogene as a very significant advance in the fight against cancer.
