Cryotherapy
Cryotherapy is a way of killing cancer cells by freezing them. It is also called cryoablation or cryosurgery.
Usually, cryotherapy is used to treat prostate cancer that has returned after an initial treatment such as radiotherapy (this is called a ‘salvage treatment’). Cryotherapy can be used to treat early localised prostate cancer but it is not known whether it is as effective as surgery or radiotherapy to treat early disease.
