RFA is used to create a localized and controlled application of:
Radiation to reduce the size of the lesion
Heat in order to induce necrosis of cells within the liver lesions
Chemotherapy drugs to kill the cancer cells within the lesion
RFA is not used to treat liver lesions
The correct answer is: Heat in order to induce necrosis of cells within the liver lesions
The choice that states RFA is used to create a localized and controlled application of heat in order to induce necrosis of cells within the liver lesions is accurate. Radiofrequency ablation (RFA) is a minimally invasive procedure that employs heat generated from radiofrequency energy to target and destroy cancerous tissues. During the procedure, an electrode is placed directly at the site of the lesion, delivering high-frequency electrical currents that produce heat. This heat absorption causes the cells to undergo necrosis, thereby reducing the tumor size and addressing the cancer in a focused manner. This option effectively reflects the primary mechanism of RFA, which is particularly beneficial for treating liver lesions, as it allows for a targeted approach that minimizes damage to surrounding healthy tissue. The precision of RFA makes it a suitable treatment option for patients with liver tumors who may not be ideal candidates for surgical resection or who have tumors that are small and localized.
