This week it has been hard to miss news on prostate cancer. The papers were full of a 'one stop shop' service for the diagnosis of the disease being rolled out in three hospitals in England. Plus celebrities have described their diagnosis and encouraged men to see their doctor for a PSA test. But just published today, the largest every study of prostate cancer over 10 years confirms that a single screening test of PSA does not save lives. With all these headlines this week is an ideal time to repeat Inside Health's prostate special. One in eight men in the UK will develop prostate cancer at some stage, but deciding who needs treatment - and when - is still far from clear. Mark Porter and Margaret McCartney report on two landmark trials that could provide some clarity, and hears from men and their doctors, faced with the dilemma of choosing the right course of action.
