Radiofrequency Ablation Effectively Treats Lung Tumors
Radio frequency ablation (RFA) is an effective and minimally invasive medical procedure which uses electrical conduction system to diagnose tumor or other dysfunctional tissue. An interventional radiologist can perform RFA procedures by using image guidance (such as X-ray screening, ultrasound or computed tomography (CT) scan). The RFA technique uses magnetic resonance imaging (MRI) that helps to guide a needle electrode into a cancerous tumor. Then high-frequency currents are passed through the electrode, which create heat to destroy the abnormal or damaged cells. The energy generated by radiofrequency closes small blood vessels and reduces the risk of bleeding.
It does not directly stimulate nerves or heart muscle, so that it can be performed without using general anaesthetic. This nonsurgical alternative treatment is proving to be good for the lung cancer patients where traditional methods are not so effective. RAF can also be performed to treat tumors in liver, kidney, bone and sometimes in other body organs. It has also been shown to have success in selective reduction procedures of multiple fetuses.
There are some common uses where RFA procedure is required, such as it is needed to treat early stage of lung cancer. It is a useful treatment for them who want to avoid conventional surgery; who have several metastases in their lung; who are too ill to undergo surgery. This treatment is considered to remove large tumor that is difficult to eliminate by surgery. In many cases this method is used to reduce the size of big tumor so that it can easily be eliminated by chemotherapy or radiation therapy. Though it is not intended to replace surgery, its conjunction with other treatments becomes more effective while treating tumors.
