Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

Additionally, knee pain might stem from your back or hips, even if you don’t feel pain there, and sitting for too long accentuates problems in these areas as well.
Radiofrequency thermocoagulation is a thermal pain treatment procedure. For example, percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) involves the placement of an electrode or catheter into the intervertebral disc and applying an alternating radiofrequency current.
He invented a method that, he said, could treat virtually all forms of cancer, [1] with no side effects, and without the need for surgery or medication. [ 1 ] [ 2 ] [ 3 ] [ needs update ] He also demonstrated a device that generated flammable hydrogen-containing gas from salt-water-solution by the use of radiowaves.
By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.
Radiofrequency ablation is a treatment that uses heat to destroy multiple small tumors. An interventional radiologist makes a tiny incision and uses either a computed tomography (CT) scan or ultrasound to guide a special needle to the site of the tumors. Next, radiofrequency (RF) electrodes are placed into the tumor.
While nephron-sparing surgery is the gold standard treatment for small, malignant renal masses, ablative therapies are considered a viable option in patients who are poor surgical candidates. Radiofrequency ablation (RFA) and cryoablation have been used since the 1990s; however, in lesions larger than 3 cm, their efficacy is limited.
