There are many forms of loco-regional therapies used as part of the arsenal against cancer to provide better control of tumors in the liver. Radiofrequency ablation (RFA)and microwave ablation (MWA) use imaging to direct a needle into a tumor target and then use heat to destroy the tumor with either electric current or microwaves.

These techniques are particularly good for small tumors in the liver – but can be also used for tumours in the lung, kidney and bone.
