Radiofrequency Ablation as a Popular Medical Procedure to Diagnose Liver Tumors

Radiofrequency ablation (RF ablation) is a less invasive treatment method to diagnose cancer. It uses different imaging techniques including computed tomography (CT) or magnetic resonance imaging (MRI) and ultrasound. This method kills cancer cells by generating heat. For that purpose physician inserts a thin needle through the skin and electrical energy delivered through this needle destroys damaged cells of the tumor. The generated heat from radiofrequency energy closes small blood vessels and decreases the risk of bleeding. After that, dead tumor cells can be replaced by scar tissue. In the treatment of liver cancer, kidney cancer, lung cancer and bone cancer, the radiofrequency ablation is proving to be very effective. It also can be combined with surgery to treat a patient who has many tumors in different locations.

At the time when surgery is not possible due to various reasons, this imaging treatment can suitably be used to avoid the risk of surgery. The RF ablation has successfully treated primary liver tumors such as hepatocellular carcinoma. It is very useful for those who are not benefitted from conventional therapies and cannot undergo surgery. Colon cancer that is the most common metastatic disease to the liver can be diagnosed by RF ablation. This treatment can be applied in conjunction with artery chemoembolization (HACE) for larger tumors.

There are some common uses of the procedure where the RF ablation is used for. Hepatocellular carcinoma and colon cancer can be treated by this method. This treatment is an effective mean for those who are not good for surgery and want to avoid its risk; those who have not enough liver tissue left for the organ; those who have several small liver tumors and have not responded to chemotherapy. It carries typically little or no pain and poses minimum risk to patient.

In many cases of liver cancers, radiofrequency ablation has proved to be effective and they have not recurred again. There are very less treatment-related complications. RF ablation is also a less expensive and provides fast recovery. It does not need surgical incision. So patients can go through easily.
