Ideally, it would be best to prevent men developing prostate cancer in the first place. But currently the causes of prostate cancer are unknown. A second option would be to cure the disease once it is diagnosed. However, for about a third of cases, the disease is fairly advanced at diagnosis and there is no cure at this late stage. Moreover, it is difficult to detect early stage prostate cancer as there are no specific signs or symptoms. Therefore there has been great interest in screening . . . . . .
