High-Intensity Focused Ultrasound, or HIFU, is a therapy that destroys tissue with rapid heat elevation, which essentially destroys the tissue. Ultrasound energy, or sound waves, is focused at a specific location, and at that “focal point,” the temperature raises to almost 90 degrees Celsius in a matter of seconds. Any tissue at the “focal point” is destroyed; however, any tissue outside of the focal point remains unharmed.
Patients who have been diagnosed with prostate cancer, or who have been previously treated with radiation therapy, may have recurrent prostate and may be candidates for HIFU treatment.
