What is Interventional
Interventional oncology is minimally invasive therapy for patients with liver, colorectal, lung, bone/soft tissue, kidney, and metastatic cancers.
Cryotherapy – also called cryosurgery, cryoablation, percutaneous cryotherapy and targeted cryoablation therapy – is a minimally invasive treatment that uses extreme cold to freeze and destroy diseased tissue, including cancer cells. Although cryotherapy and cryoablation can be used interchangeably, the term "cryosurgery" refers to performing cryotherapy using an open, surgical approach.
How it Works
During cryotherapy, liquid nitrogen or high-pressure argon gas flows into a needle-like applicator or cryoprobe, creating an intense cold that the interventional radiologist uses to freeze and destroy diseased tissue. To visualize the treatment sites, physicians will use ultrasound or CT to help guide the cryoprobes within the body.
It is used for prostate, liver, and cervical cancers, especially if surgery is not possible. Cryotherapy also treats tumors in the kidneys, bones (including the spine), lungs and breasts.
