Soon, we may be able to use an early warning test to detect breast cancer.
British scientists have come closer to developing such a test, which could save the lives of millions of women.
They have discovered five more cancer-causing genetic mutations on top of the 13 already known.
"By finding more of these genes we may be able to develop a test that can predict more reliably a woman's risk of developing breast cancer," the Daily Express quoted Professor Doug Easton of Cambridge University as saying.
His report is published in the journal Nature Genetics.
