What is Interventional
Interventional oncology is minimally invasive therapy for patients with liver, colorectal, lung, bone/soft tissue, kidney, and metastatic cancers.
Radiofrequency ablation (RFA)
Radiofrequency ablation (RFA) is a minimally invasive treatment option for cancer. This image-guided technique uses heat to destroy cancer cells and can treat cancerous lesions within the liver, lungs, kidneys and bones. After the procedure, dead tumor cells treated by the extreme heat are broken down overtime by the immune system, which leaves a small scar at the site.
How it Works
RFA uses ultrasound or computed tomography (CT) to help guide a needle electrode into the cancerous tumor. RFA passes high-frequency electrical currents through the electrode to ground pads placed on the body, which creates focused heat that destroys the cancer cells surrounding the electrode.
