This procedure is usually performed while the patient is put to sleep (general anaesthesia). In this procedure, a special needle (Radiofequency or microwave probe) which produces heat at the tip of the needle is inserted through a small hole in the skin into the tumour under imaging guidance. The heat generated from the needle tip is used to burn and kill the tumour cells completely. This treatment is as effective as open surgical removal for small tumours (generally 3 cm in size) in the liver, kidney or lungs without the major side effects/ complication risks of open surgery. This is also suitable for elderly/ frail patients who are not ideal for open surgery.
