A new noninvasive therapeutic application using ultrasound-guided, high-intensity focused ultrasound (HIFU) is currently being employed for a specifically localized ablation with no skin damage. The ultrasound waves are focused on a small area where the rise in temperature leads to tissue necrosis. This precision avoids injuring healthy tissues around the lesion. The echotherapy is a technique that enables clinicians to visualize and simultaneously treat a tumor such as fibroadenoma with no incision or scar.
