This information explains how to prepare for and what to expect when you have your ablation procedure at Memorial Sloan Kettering (MSK).
Ablation is a minimally invasive procedure that uses special needles to apply heat, cold, lasers, or chemical agents to destroy cancer cells. The ablation reaches the tumor through a special needle. You will need to have imaging tests done to guide the placement of the needle into the tumor. These imaging tests may be a computed tomography (CT) scan, magnetic resonance imaging (MRI), or an ultrasound. Once the needle reaches the targeted area, the ablation therapy will deliver the selected agent to destroy the cancer cells.
Your ablation will be done by a doctor in Interventional Radiology (IR). The IR doctors specialize in image guided procedures and will use scans during the procedure to help guide the placement of needle into the tumor. Your doctor will speak with you about the type of ablation that is best for you.
Before Your Procedure
You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you to stop. We have included some common examples below.
If you take medication that affects the way your blood clots, ask the doctor performing your procedure what to do. The doctor’s contact information is listed at the end of this resource.
Some examples of these medications are:
drugs (NSAIDs) such as ibuprofen
(Advil®) or naproxen (Aleve®)
Whether your doctor recommends you stop taking it will depend on the reason you are taking it. Do not stop taking any of these medications without talking with your doctor.
- Please review the information in the resource Common Medications Containing Aspirin and Other Nonsteroidal Anti-Inflammatory Drugs (NSAIDs). It includes important information about medications you’ll need to avoid before your procedure and what medications you can take instead.
- If you take insulin or other medications for diabetes, you may need to change the dose before your procedure. Ask the doctor who prescribes your diabetes medication what you should do the night before and the morning of your procedure.
You must have someone 18 years or older take you home after your procedure. If you don’t have someone to do this, call one of the agencies below. They will provide someone to accompany you home; however, there is usually a charge for this service and you will also need to provide transportation.

During Your Procedure
You will be assisted onto the procedure table. Your legs may be shaved to allow for placement of pads that are required for your procedure.
Your skin will be cleaned with an antiseptic and covered with sterile drapes. A local anesthetic will be injected in the area where your doctor will be working to make it numb. Images of the area will be taken so that the needle can be placed in the tumor. When the needle is in the right place, your ablation will begin.
After your ablation, a small dressing will be placed on the site where the needle was inserted.Back to top
