Radiofrequency Ablation: A Popular Method to Kill Kidney Tumors by Less Invasive Mean
Radiofrequency ablation (RF ablation) is a minimally invasive treatment for cancer. This treatment can suitably be used when surgery is not possible due to various reasons and when medical conditions add the risk of surgery. RF ablation is used to kill cancer cells by heating and destroying them. Here, physician inserts a thin needle, guided by computed tomography (CT) or ultrasound, through the skin. The electrical energy delivered through this needle destroys the tumor. At the same time, heat from radiofrequency energy closes small blood vessels and reduces the risk of bleeding. And then dead tumor cells are gradually replaced by scar tissue. This technique is very effective to diagnose kidney tumor, liver cancer, bone cancer and lung cancer.
There are several advantages of RF ablation of kidney cancer. It is proved to be an effective treatment for small tumors and can be executed with no skin incision. Radiofrequency ablation uses some imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI) and ultrasound, because they help to guide needle electrode into a cancerous tumor.
It has typically little or no pain and poses minimum risk to patient. Probably surgery is the primary treatment for most kidney tumors but for some specific reasons the radiofrequency ablation can be considered. Mainly these reasons are as patients living with one kidney, those who have other medical conditions which might prevent surgery, to resist the risk of surgery or post-surgical recovery, and those patients who have tumors of less than 4 centimeters in size. So, radiofrequency ablation of kidney tumors has become a popular treatment because of these advantages.
