Focal therapy can avoid damage to normal prostate while tackling appropriately diseased and cancerous tissue. It may have lesser side effects because not all of the prostate is destroyed.
Focal therapy is an emerging treatment option that involves the focal ablation of prostate cancer with preservation of surrounding healthy tissue. This approach might result in reduced morbidity when compared with whole-gland therapies. In current practice, much controversy surrounds optimal patient selection and preoperative tumour localization strategies. Focal therapy modalities include cryotherapy, high-intensity focused ultrasound, laser ablation, photodynamic therapy, irreversible electroporation, radiofrequency ablation and focal brachytherapy.
