Cryoablation is a minimally invasive procedure that uses extreme cold to freeze and destroy targeted tissue. This cryotherapy technique involves the application of either liquid nitrogen or argon gas directly to abnormal tissues. Cryoblation has various applications, including managing chronic pain associated with certain types of cancer. A palliative cryoblation helps disrupt pain signals sent from the affected nerves to the brain, providing potential pain relief. Here is more information on treating chronic cancer-related pain and tumors with cryotherapy:
How Cryoablation Works
Cryoablation is a minimally invasive procedure that utilizes extreme cold to target and shrink tumors. During the process, imaging guidance is used to position one or more cryoprobes directly into or around the tumor. Cryoprobes deliver freezing temperatures by cycling pressurized gas, enveloping the tumor tissue in cold temperatures. The intense cold disrupts cellular function, causing ice crystals to form inside the tumor cells, which leads to cell membrane rupture and eventual cell death. The body naturally absorbs and removes the damaged tissue over time.
Cryoablation is particularly effective for treating small, localized tumors and is used across various fields, including oncology, as a precise, less invasive alternative to traditional surgery. This cryotherapy method targets the source of cancer-related pain by focusing on the specific areas that are sending pain signals. During the procedure, a physician uses imaging guidance, like a CT scan or ultrasound, to precisely place a thin, needle-like cryoprobe.
The cryoprobe delivers intensely cold gas, which creates an ice ball around its tip. The ice ball engulfs the targeted nerve tissue, and the freezing temperatures cause cell death. This effectively interrupts the nerve’s ability to transmit pain signals to the brain. The body’s natural processes then clear away the destroyed tissue over time.
Who Cryoablation Is Recommended For
Cryoablation may be used for individuals experiencing chronic cancer pain that has not responded well to other pain management treatments, such as medication or radiation therapy. It is often used for well-localized pain, meaning it originates from a specific, identifiable area. This can include pain from tumors that have spread to bone (metastases) or from tumors pressing on nerves. A medical team will evaluate a patient’s overall health, pain location, and pain severity. They will also evaluate previous treatments to determine if cryoablation is a suitable course of action.
What the Procedure Process Is Like
The cryoablation procedure is typically performed on an outpatient basis. Before it begins, the patient is given local anesthesia to numb the area where the cryoprobe will be inserted, and they may also receive light sedation to help them relax. Using imaging guidance, the physician inserts one or more cryoprobes through the skin and guides them to the exact location of the targeted nerve or tissue.
Once the probes are in position, the freezing process begins. The physician carefully controls the flow of the freezing agent to create an ice ball of a specific size and shape to encompass the target area while avoiding damage to surrounding healthy tissue. The freezing cycle is often followed by a thawing cycle, and this freeze-thaw sequence may be repeated to effectively destroy targeted cells.

Cryoablation helps manage chronic pain related to cancer by using extreme cold to interrupt nerve signals and shrink tumors. It can be a valuable option for patients with localized pain that is difficult to control through other means. The procedure is minimally invasive and focuses directly on the source of discomfort. If you are experiencing cancer-related pain, discuss cryotherapy options with your healthcare team today. Radiology specialists can help you find the most appropriate path for your specific situation.
