HIFU treatment for prostate cancer is administered to the patient under light anesthesia. A special probe is inserted rectally to deliver high-intensity focused ultrasound (HIFU) waves to the cancerous region of the prostate. The absorption of these waves by the tissue generates a targeted temperature increase of 85-100 degrees Celsius, destroying only the cancerous cells. This approach ensures that the surrounding healthy prostate tissue is preserved, providing a precise and targeted treatment.
