Almost 48,000 men are diagnosed with prostate cancer in the UK every year. But questions are being asked of the tests used to diagnose these men, and how they might be improved. The tests used today can be painful, invasive and, unfortunately, not that good at telling doctors for sure which cases need urgent attention, or which can be watched over time. This challenge is most apparent when looking at the results of screening studies in men without prostate cancer symptoms using the PSA blood test.
