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??
In: Biology
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.
The goal of cryotherapy (and most cancer therapies) is to kill all of the cancer cells while killing the fewest possible normal cells. But it will kill normal cells as well.
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.
