HIFU is a radiation and surgery free treatment for prostate cancer, using high-intensity ultrasound waves to heat and destroy cancer cells within the prostate. Because traditional treatments for prostate cancer often in significant side effects including incontinence and erectile dysfunction, men are looking for other solutions. These can be minimized using high intensity focused ultrasound (HIFU) for treatment of prostate cancer. There is no invasive surgery involved. Sound waves are focused with laser like precision to ablate prostate tissue, without harm to surrounding structures. Focal therapy, meaning treating only the cancerous portion of the prostate, can be accomplished without disturbing the normal prostate tissue.
