If you have early-stage prostate cancer, your doctor might choose to kill cancer cells by freezing them. He’ll put small needles or probes into your prostate to deliver very cold gasses that destroy the cells. This procedure is known as cryotherapy.
It’s hard to say for sure how well it works. Scientists haven’t done much long-term research that focuses on using it to treat prostate cancer; therefore, it's usually not the first treatment option for most doctors.
