Focal therapy for prostate cancer has emerged an interesting concept as a less morbid option for the treatment of localized low-risk disease. Despite the growing interest in focal therapy, this approach has not yet gained sufficient popularity nor provided enough data to be discussed outside the experimental application. Herein we summarize the available data on focal cryotherapy and focus on the targets to be achieved in order to increase the applicability of focal cryotherapy to clinical practice. A cautious approach to candidate selection and generation of solid scientific data that would result in wide consensus on patient selection strategies and follow-up schemes would provide the tools necessary to take the path of focal therapy. Currently available focal cryotherapy data demonstrate excellent short-term results and a favorable quality-of-life profile. Although the future role of focal treatment is debated, a growing amount of science is generated in support of this minimally invasive approach.
