HIFU is a precise and targeted therapy that reduces the risk of complications and impact to quality of life caused by surgery and radiation. HIFU uses ultrasound energy, or sound waves, to heat and destroy specifically targeted areas of tissue. During HIFU, the sound waves pass through healthy tissue without causing damage. However, at the focal point of the sound waves the tissue temperature rises rapidly to 90 degrees Celsius destroying the targeted tissue. The same principles are used when light is focused through a magnifying glass.
