This treatment uses heat to destroy cancer cells. It's usually only used when a person has a very early-stage cancer and other treatments are not suitable.
You’ll be given a local anaesthetic and sedation before the treatment begins. In some cases, general anaesthetic is used instead. Your 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 destroy the cancer cells.
There are very few side effects with this treatment, although it's common for people to have some pain or discomfort and to feel tired afterwards. You'll usually need to stay in hospital overnight for this treatment.
