Radiofrequency is the application of electromagnetic waves, which produce heat in the tissue where it is applied, leading to a necrosis or cell death. The body reacts to this necrosis by absorbing this tissue; therefore the tumours in which they are applied reduce their volume.

The radiofrequency technique has been used since the 90s in liver tumours and thyroid tumors. Currently, radiofrequency is the first line of treatment used in liver cancer, ahead of surgery. Fewer and fewer surgeons have to intervene on the thyroid, with the risks that surgery entails in this organ, because radio frequency manages to successfully treat many of the thyroid tumours.

Use of radiofrequency for the treatment of myomas is more recent. It began to be used ten years ago, not vaginally, by Italian specialists, who used this technique during the surgery they performed, precisely because they could not remove some myomas that were inaccessible. All the studies published so far show that myomas reduce between 60 and 70% of their volume a year after the application of radiofrequency.

In breast cancer, radiofrequency is currently being used after the removal of breast cancer to avoid the need for subsequent radiation therapy and recurrences.
