Researchers in Britain have identified a faulty gene copy that increases the risk of ovarian cancer among women by more than 600 percent.
The study, conducted by researchers from Britain's Institute of Cancer Research, involved more than 910 women who had ovarian or breast cancer with the researchers comparing their DNA with more than 10,000 women in a control group.
The researchers concentrated on a gene known as RAD51D and found that those who suffered from cancer had eight faults in the gene compared to just one fault in the DNA from the control group. The study has been published in the journal Nature Genetics.
"Women with a fault in the RAD51D gene have a one in 11 chance of developing ovarian cancer", lead researcher Nazneen Rahman said.
