Radiofrequency Ablation (RFA) is a medical procedure that uses heat generated by radio waves to destroy abnormal tissue in the body. It is commonly used to treat conditions like tumors, arrhythmias, and chronic pain. During the procedure, a thin needle is inserted into the targeted area, and radiofrequency energy is applied, causing the tissue to heat up and ultimately die off. This technique is minimally invasive, meaning it often requires only small incisions or no incisions at all. Patients typically experience less pain and a quicker recovery compared to traditional surgery. RFA can be performed in various settings, including hospitals and outpatient clinics.
