A simple blood test may be able to determine whether men are at risk of developing prostrate cancer, research shows.
Experts say the test may be especially useful in men with a family history of prostate cancer.
Senior researcher Jianfeng Xu said: "This is significant and could affect clinical care.
"The information could substantially improve physicians' ability to assess risk and determine the need for more aggressive screening or even a biopsy."
Currently, age, race and family history are the three factors associated with increased risk of prostate cancer.
"Our finding provides an opportunity to supplement the well-established risk factors by looking at how many of these variants a man has inherited," said Xu.
"It may provide a much better weapon to guide clinicians."
The researchers add, however, that further study is needed to determine how a blood test may complement prostrate-specific antigen testing.
