Eli5: How does cryotherapy kill cervical cancer cells?

Question

I just learnt about cryotherapy in treating cervical cancer. How do they manage to freeze cancer cells that are inside the body without damaging normal healthy cells??

Answer 1

The cancer cells aren’t hidden inside the body, there’s a lump on the cervix that can be frozen and killed. This kills healthy cells too, but mostly cancerous ones.
