What is tumour ablation done with?

The probe delivers energy or another treatment directly to a targeted area. Radiofrequency ablation uses electrical energy to produce heat; microwave ablation uses microwaves to heat tissue. Other ablation methods may use cold or injected substances, depending on the tumour and the treatment plan. Imaging such as ultrasound, computed tomography, or magnetic resonance imaging can help the clinician guide the probe and monitor its position.

The procedure may be performed through the skin or during surgery. Suitability depends on the tumour’s size, location, number, nearby organs, and your general health.

Ask how you should prepare, including instructions about food, medicines, and transport home. Afterward, rest as advised and keep the puncture site clean and covered. Mild soreness can occur. The [Radiofrequency Ablation System](/technology/radiofrequency-ablation-system/) is one type of equipment, while [Tumour Ablation](/treatments/surgical-oncology/tumour-ablation/) describes the treatment approach.

Call the treatment team for persistent bleeding, increasing redness or swelling at the probe site, fever, worsening pain, new weakness, or a change in breathing. Seek urgent care for severe chest or abdominal pain, confusion, fainting, or sudden difficulty breathing.

Ask which energy or method is planned, how the probe will be guided, whether sedation or anaesthesia is needed, what nearby structures must be protected, and how treatment response will be checked.
