Radiofrequency ablation and microwave ablation

What is ablation?

Radiofrequency ablation (RFA) and microwave ablation (MWA) use heat to destroy cancer cells. 

When it is used?

Ablation treatments are sometimes used to treat very early-stage lung cancer. They can also be used when lung surgery may not be a suitable treatment option.

Having ablation treatments

You’ll be given a local anaesthetic and sedation before treatment begins. In some cases, a general anaesthetic is used instead. 

Your doctor will place a small needle-like probe into the lung tumour through your chest. This is usually done using a CT scanner to make sure the probe is in the right place. Radiowaves or microwaves are then passed down the probe into the tumour to heat and destroy the cancer cells.

After ablation

It is common for people to have some pain or discomfort and to feel tired after RFA or MWA. You will be given painkillers to take home. You’ll usually need to stay in hospital overnight for these treatments. RFA and MWA can be repeated if necessary.

These treatments are not available in every treatment centre.
