Percutaneous Radiofrequency / Microwave Ablation 

Percutaneous Radiofrequency  or Microwave ablation is a minimally invasive procedure to treat cancer. Cancer cell is killed by heat generated by radio waves or microwaves. It is performed by the interventional radiologist in the CT scanning room. Under ultrasound and CT guidance, through a tiny skin incision, a probe (antenna usually less than 2-3mm diameter) is inserted into the tumour. The probe is connected to a generator that delivers radio waves or microwaves into the probe’s tip. This heat energy kills the cells in a small area around the probe tip. 

Depending on the tumour’s size, the probe may be guided and repositioned during the procedure to try to destroy the whole tumour. A small margin of normal tissue near the tumour is also destroyed to ensure complete ablation. 


Are there risks from ablation?
