How is cryotherapy done for prostate cancer?

ANSWER

Cryotherapy uses very cold temperatures to freeze and destroy cancer tissue. Your doctor inserts a very think metal probe or needle into your prostate gland. It goes through a tiny cut on your skin between your bottom and the scrotum. A warm saline solution flows through a thin tube during the procedure to protect your urethra, which empties your urine.

The surgeon uses images from the ultrasound to spot the cancer tissue. They then use a freezing liquid, such as liquid nitrogen or more commonly, argon gas, to freezes the prostate and destroy any cancerous tissue inside.
