Ultrasound has been used for decades to break up kidney stones...this is just a step up. One worry...in animal studies only 80% had full tumor elimination. What happened in the other 20%?
Different technologies. Extracorporeal shockwave lithotripsy uses shockwaves, which are pressure waves made of “white noise,“ to distort and break up stones. It works because kidney stones are much denser than anything in the body, even bones, so the pressure waves travel through the body until reaching the stone. HIFU, or high-intensity focused ultrasound, uses sound waves at a certain frequency that heats the targeted tissue to destroy cancer cells. It has been used in Europe and other parts of the world for years, but the FDA has been slow to approve it for the US. It is a promising alternative to radiation therapy and cryosurgery.
