How Do I Know That Cryosurgery Worked?

Question: How do I know that cryosurgery worked?

Answer: I check PSA blood test levels five weeks after the cryosurgery has been done. And then the patient's PSA levels are followed at three to six-month intervals -- the same as we would after surgery or radiation. And based on the PSA changes following the cryosurgery, we can gauge the success of the treatment.
