Cryotherapy freezes tissue within the prostate gland. After being frozen, the prostate cancer cells die.
Your doctor may recommend cryotherapy for prostate cancer as an option at different times during your cancer treatment and for different reasons, including:
- As the only (primary) treatment for cancer, usually for early-stage cancer that is confined to your prostate
- After other cancer treatment, such as radiation therapy, to stop the growth of prostate cancer that has returned (salvage therapy)
