Radiofrequency ablation uses heat to destroy cancer cells. A doctor will place a needle into the lung tumour. This is usually done using a CT scanner to make sure the needle is in the right place. Radiowaves are then passed down the needle into the tumour to heat, and so destroy, the cancer cells.

This treatment is usually only used when a person has a very early stage cancer and other treatments are not suitable.

There are very few side effects with this treatment although it is quite common for people to have some pain or discomfort and to feel tired. You usually need to stay in hospital overnight with this treatment.
