This book comprehensively reviews the potential of focal therapy and discusses why the changing face of prostate cancer warrants a change in the way we treat men with the disease. It deals with the mechanisms by which disease can be localized within the gland and then the different technologies used for focal ablation. Bringing together eminent contributors in one accessible reference, this book introduces focal therapy to all urologists, oncologists, and radiologists who are involved in the treatment of men with prostate cancer.
