Prostate cancer is a very common form of cancer in the western world, where prevalence in Sweden is among the highest in the world. In order to make a diagnosis biopsies of the prostate are required. The main objective of the project is to reduce the number of infections associated with prostate biopsies. A secondary effect resulting from safe biopsies can be a more liberal attitude to biopsying and the earlier detection of prostate cancer. The technique should also reduce bleeding after biopsying.
