Electrosurgery involves the use of radiofrequency medical devices to generate electrical energy to “burn” off a skin lesion / growth. Any smallish skin lesion that is growing in size, causing pain or unsightly can be removed with electrosurgery without leaving any major scar.

We start treatment once adequate anaesthesia is achieved and the actual treatment is fairly quick. Some patients are amazed at how fast the whole process takes. No sutures are used, so a follow up visit is not necessary; unless Dr Wong requests a review visit to supervise the wound healing progress.
