An international study suggests men who consume two or more standard drinks a day increase their likelihood of developing prostate cancer by 20 per cent.

The research by scientists from Australia, Canada and the United States, examined 35 previous studies from around the world.

The findings back the new alcohol consumption guidelines announced by the National Health and Medical Research Council earlier this month.

One of the contributors was Tanya Chikritzhs of the National Drug Research Institute.

Associate Professor Chikritzhs, from Western Australia's Curtin University, says her team had to separate each study before it came to its conclusion.

She says the risk increases along with the number of drinks consumed.

"The risk increases along what we call a curve, so it's not a straight up and down line," she said.

"So at two your risk is 20 per cent, at 3 your risk is 25 per cent, at 6 standard drinks is about 35 per cent and then 45 per cent at 8 standard drinks.

"What we did was pull apart the studies themselves and separate out the different types of designs and it was in doing that that we could identify that the prostate cancer alcohol link was lost underneath layers of confounding and biasing certain types of studies."
