The prostate cancer mortality rate in the US has fallen at four times the rate of that in the UK since screening has become more commonplace, it has been revealed.
However, researchers have cautioned that the screening programme may not be the decisive factor behind the rapid decline.
By 2001, close to 60 per cent of men over the age of 50 in the US had undergone a prostate cancer screening test in the previous 12 months - compared to the six per cent of men aged 45 to 84 tested in the UK between 1999 and 2002.
Researchers found that the upsurge in screening in the US coincided with a decline in the rate of prostate cancer mortality which at 4.17 per cent per year is nearly four times higher than the equivalent rate in the UK.
The NHS is reluctant to offer the tests, though, as screening has been found to be inaccurate.
The study appeared in Lancet Oncology and was carried out by a team from the University of Bristol.
