Radiofrequency or radiowave surgery can be used for minor surgical procedures such as removing thread warts, or growths.It involves the passage of radio waves into the skin to perform the removal or reshaping of a lesion. Different types of electrodes are used depending on the type of lesion, e.g. fine needle, wire loop, scalpel blade etc. Expect minor swelling, redness, bruising and tenderness in the area for a few days as it heals. There should not however be any bleeding due to the tissue coagulation during treatment.
