Cryoablation is a medical procedure used to treat certain tumors, and it provides a minimally invasive alternative to traditional surgery. This treatment uses extreme cold to destroy abnormal tissue, which may be a suitable option depending on your specific medical condition. Understanding this procedure can help you know what to expect during treatment. Here is more information on cryoablation, including how it works and what the process involves:
What Is Cryoablation?
Cryoablation is a medical procedure that uses freezing temperatures to destroy diseased tissue, including cancerous tumors. It is a type of cryosurgery, and it is performed by interventional radiologists specializing in minimally invasive, image-guided treatments. This technique is applied to a variety of conditions and can target tumors in the bone, kidney, liver, lung, and prostate.
The primary goal of cryoablation is to eliminate abnormal cells while minimizing damage to surrounding healthy tissue. Using imaging guidance, such as ultrasound or computed tomography (CT), a specialist can precisely locate the target area for treatment. The procedure is an option for patients who may not be candidates for conventional surgery due to health reasons or tumor location.
How Does It Work?
Cryoablation functions by delivering intensely cold gas through a small, needle-like probe directly into the targeted tissue. This probe, called a cryoprobe, rapidly freezes cells, forming ice crystals inside and around them. These ice crystals disrupt the cell membrane, leading to cell death.
The process involves a freeze-thaw cycle, often repeated to maximize the destruction of abnormal tissue. After the initial freeze, the tissue is thawed briefly before being frozen again. This cycle further damages the targeted cells and the small blood vessels that supply them, effectively cutting off their blood supply.
Following the procedure, the body’s natural immune system clears away dead cells over time. The targeted tissue is gradually absorbed and removed by the body, which helps in the healing process. This method of tissue destruction is controlled and localized to the treatment area, and a specialist helps determine if this treatment is beneficial for each situation.
What Does the Process Involve?
Before the procedure begins, the treatment area will be sterilized. You may receive sedation to minimize pain, and your medical team will monitor your vital signs throughout the procedure. Using imaging guidance, the interventional radiologist will insert one or more cryoprobes through the skin and into the tumor. Once the probes are correctly positioned, the freezing gas is circulated, and the targeted tissue is frozen.
After the freeze-thaw cycles are complete, the cryoprobes are removed, and a small bandage is applied to the insertion site. The entire procedure may take several hours, depending on the size and location of the tumor being treated. You will be moved to a recovery area for observation before being discharged.
What Are the Benefits?
Cryoablation is minimally invasive, often resulting in less pain, a shorter recovery period, and minimal scarring. Most patients can return to their normal activities within a few days. The treatment can also be repeated if necessary, and it does not preclude future treatment options.

Cryoablation is a targeted treatment that uses extreme cold to destroy abnormal tissue, offering a minimally invasive option for certain conditions. It works by freezing and thawing cells, which destroys them while preserving surrounding healthy tissue. The procedure involves precise, image-guided probe placement and generally has a short recovery time. If you want to learn more about this treatment, speak with your doctor to discuss your options.
