Liver Ablation

What Is Microwave Ablation (MWA)

Unfortunately, not all liver tumours can be removed by surgery. If you have received this diagnosis, there is an option of a minimally invasive procedure, which can assist in treating the tumour.

Read more about what to expect from this procedure in our Radiofrequency Ablation Patient Information.


When Is This Procedure Conducted?

A non-surgical, minimally invasive procedure called Liver Ablation is performed when a liver tumour is inoperable. This is called Microwave Ablation (MWA), a localised treatment that kills the tumour cells with heat, while sparing the healthy liver tissue.


How Does This Procedure Work?

The interventional radiologist will guide a small needle through the skin into the tumour. Microwave energy is transmitted to the tip of the needle, where it produces heat in the tissues killing the cells. The dead tumour tissue shrinks and slowly forms a scar.


How Will I Feel After The Procedure?

Unlike systemic therapy (chemotherapy, medications), this treatment is much easier on you. Typically you are able to resume your usual activities within a few days.


How Successful Is Liver Ablation?

Depending on the size of the tumour, MWA can kill the tumour, extending your survival time and greatly improving the quality of your life while living with cancer. Because it is a local treatment that does not harm healthy tissue, the treatment can be repeated as often as needed. MWA is a very safe procedure, with complication rates around two to three percent.

MWA is effective for small to medium-sized tumours.


Summary of Benefits of Liver Ablation

  • Is most effective when all the cancer is localised in the liver
  • Can be used to treat primary liver cancer and tumours that have metastasized (spread) from other areas in the body to the liver
  • Is well tolerated-most patients can resume their normal routine the next day but may feel tired for a few days
  • Can be repeated if necessary
  • May be combined with other treatment options
