Radiofrequency ablation (RFA) uses radio waves to kill cancer cells. A small probe, similar to a needle is passed into the lung tumour through the skin over your chest into the lung. The radio waves are then passed through the probe to heat the tumour and destroy the cancer.
The treatment is usually carried out using a CT scanner to check the probe is in the correct position. It may be a little uncomfortable and cause tiredness. Often RFA will involve an overnight stay in hospital.
