Radiofrequency ablation (RFA) is one of the treatments for tumors such as liver cancer or kidney tumors. The radiofrequency ablation procedure uses a special device that generates high frequency radio waves. These radio waves are delivered directly to the tumor through a needle or applicator, which is inserted into the tumor using images, for example, using ultrasound scanning or computed tomography (CT).
When radio waves reach the tumor, they create heat that destroys the tumor. This process is called ablation. The heat generated by the radio waves causes the coagulation of proteins inside the tumor, which eventually leads to the destruction of the tumor.
The advantages of radiofrequency ablation include a small number of complications, minimal invasiveness of the procedure (usually only a small skin opening is required) and rapid recovery after the intervention. This method is usually considered for patients who cannot undergo routine surgery or who have contraindications to chemotherapy.
It is important to remember that the decision on the treatment method should always be made individually by the doctor, taking into account all the characteristics of the disease and the patient's condition.
