Once you've destroyed the tumor, how do you get it out of the body?

The recycling of dead cells is a normal biological process the same thing happens when they use radiation to kill cancer cells

If I interpret the article correctly, the ultrasound energy does two things: it effectively destroys the cancer cells by overheating them, and it physically breaks apart the tumour. Your immune system can further break up and get rid of dead cells the way it deals with normal dead cells.

  • Won't there still be some broken up live cells that can now migrate around the body and cause cancer in other areas?

    • This was an issue with uterine morcellation; https://en.wikipedia.org/wiki/Morcellator. Per the article, though:

      > Some researchers have raised concerns about histotripsy potentially seeding new cancer growths as tumours are broken up inside the body, meaning they can be transported to other areas. That fear, however, hasn't borne out in animal studies so far.
