Cryotherapy is the use of extreme cold to destroy abnormal or diseased tissue.
We use cryotherapy to treat lung cancer tumors, as well as obstructions in the airway and other parts of the body.
During cryotherapy, liquid nitrogen or argon gas flows through a long, thin insulated tube. Using image guidance, your doctor places a probe on the tumor or obstruction and freezes the cells. After the procedure, the tissue is absorbed by the body or removed by your doctor.
Cryotherapy may be an effective treatment for lung cancer tumors that cannot be removed by surgery. Cryotherapy can also be a life-saving option for patients with obstructions in the airway, especially those who have a stent and would not be candidates for other interventional pulmonology procedures.
