    The sound waves are focused onto the tumor, so they only have enough energy to damage tissue there, and not anywhere else.

    Think about focusing the sun’s rays through a magnifying glass; they’re only concentrated enough to burn at a very small area. The focused ultrasound is similar, although they’re probably using some form of phased array to get the equivalent effect.
