Research into prostate cancer is now focused on finding a test to sort aggressive tumours, known as 'tigers', from the harmless ones, the 'pussycats'.
Around 3,172 new cases of the disease are diagnosed every year in Irish men. But health experts agree that the current examination, the PSA (prostate-specific antigen) test, has major limitations in assessing prostate cancers. In particular, it cannot determine whether a prostate cancer is slow or fast growing.
This means that many thousands of men are being given invasive treatment that they don't need.
Research has focused on identifying markers that can be used to distinguish harmless from aggressive prostate cancers.
