High-Intensity Focused Ultrasound (HIFU) is a non-invasive therapeutic procedure that employs focused ultrasound waves to target and treat specific tissue areas in the body, particularly useful in oncology for cancer treatment. The procedure begins with the administration of a local anesthetic or sedative to ensure patient comfort. The patient is then positioned appropriately based on the location of the target tissue. Using real-time imaging techniques such as MRI or ultrasound, the physician identifies the precise location of the targeted area. Once the target is confirmed, the HIFU device emits high-frequency ultrasound waves that converge at a specific point within the tissue. This focused energy raises the temperature of the targeted cells, causing thermal ablation which effectively destroys the tissue.

Throughout the procedure, continuous imaging ensures that the ultrasound waves are accurately concentrated on the lesion or tumor, avoiding damage to surrounding healthy tissues. The process is meticulously monitored and adjusted as needed to ensure efficacy and safety. Depending on the target area's size, the HIFU treatment duration can vary from one to several hours. Post-procedure, patients are usually observed for a short period for any immediate complications before being allowed to return home. Due to its non-invasive nature, HIFU generally involves minimal recovery time, allowing patients to resume regular activities relatively quickly. The efficacy and safety of HIFU make it a valuable option for patients seeking a less invasive alternative to traditional surgical methods.
