Some prostatecancer patients are good candidates for cryoablation. health
A: Prostate cancer is the second-most-common type of cancer in men. Only skin cancers occur more often. This type of cancer arises in the prostate gland, which is about the size and shape of a walnut and is located beneath the bladder.
Therapies may consist of one or more approaches, including surgery, radiation, chemotherapy, hormone therapy or immunotherapy. Cryoablation, also known as cryotherapy, can also be an option in certain cases. This is a procedure in which abnormal tissues are subjected to extremely cold temperatures, which destroys the cells.
There are two forms of cryotherapy for prostate cancer. One type, known as whole-prostate cryotherapy, treats the entire gland. This kills both the cancer cells and the healthy tissues. Freezing the tissues of the prostate gland often damages the nearby nerves that control erections. As a result, erectile dysfunction occurs more often after whole-prostate cryotherapy than when the gland is surgically removed.
In both types of cryotherapy, a catheter filled with warm saltwater is used to protect the urethra. This is the tube that empties the bladder. The catheter is left in place for several weeks after the surgery, which ensures the patient can empty his bladder as he recovers.
