Cryotherapy is one of the latest treatments, which is being evaluated for its use in early stages of prostate cancer. This treatment kills cancer cells by freezing them. Freezing is carried out by placing a frozen liquid (liquid nitrogen or argon) through the needle directly into the prostate gland. The procedure is performed under ultrasound imaging guidance.
According to an American Cancer Society study prostate cancer is the most common type of cancer for men between 50 and 60 years old and more than 200,000 men are diagnosed with this type of cancer annually. Even if the cancer is diagnosed in its early stages and treated, 30% to 40% of men deal with a recurrence of prostate cancer. Cryotherapy is still being studied to determine which patients could benefit from it. For example, studies are underway to determine if cryotherapy is beneficial as an initial treatment for organ-confined (localized) prostate cancer.
