Who is a Candidate? 


Your doctor may recommend microwave ablation if you cannot undergo surgical cancer treatment because the tumor is too difficult to reach or your health makes surgery too risky. 

You may also receive microwave ablation as part of palliative care to shrink tumors and ease cancer symptoms like pain.

Microwave ablation can also be given along with chemotherapy, radiation therapy, or even other surgeries to improve the effectiveness of cancer care.


What to Expect


Your doctor may tell you not to eat or take certain medications, like aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) before your procedure. Always tell your doctor what medicines you are taking, including vitamins or herbs.

During microwave ablation, you will be sedated or under general anesthesia, meaning you will be asleep during the procedure. Your doctor will also apply local anesthetic (numbing at the site of the procedure) to the area being treated so you won’t feel pain.

Once you are numbed, your doctor will use imaging technology, like computed tomography (CT) scans, to locate the cancer cells. They will then insert a needle into the cancer cells. After the needle is in place, electromagnetic waves flow through the needle and heat up the cells to destroy them. 

After your doctor has destroyed as many cancer cells as possible, they will remove the needle and put a bandage or dressing on the injection site. Altogether, your procedure may take 30 minutes or a few hours, depending on how many areas need to be ablated (destroyed). You may be able to return home a few hours after surgery. You can typically resume normal activities within a few days.
