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

It’s used to kill abnormal cells on the cervix. They do this by opening up the vagina and putting a cryoprobe against the cervix which will kill the abnormal cells. This is likely to kill some of the healthy cells too.
