Cryosurgery is the controlled application of extreme cold
to kill cancerous tissue. The procedure freezes the cancer
cells and directly kills them. It also freezes the blood supply
surrounding the tumor, thereby starving the tumor even if
some cells survive.
Cryosurgery is being utilized in the treatment of both prostate
cancer and cancer that affects the kidney. The use of minimally
invasive cryosurgery often results in less pain, minimal bleeding
and a shorter recover period then traditional open surgery
for removal of cancerous tumors.
