I've had personal experience with Derma Correct Skin Tag Removal Review this option as my wife has had several moles surgically removed by this method. It basically involves a surgeon cutting out the mole as well as the surrounding areas to make sure nothing is missed. The wound is then stitched up to allow it to heal naturally. This method does leave a scar but it will fade over time. If you have a cancerous mole it will most likely by removed by this method.
This method has less scarring than the previous method and due to this is more popular with moles on the face. It involved burning the mole off close to the skin and due to the cauterization the bleeding is stopped and infection is much less likely. Cauterization used to be the preferred method for preventing infection before the invention of antibiotics.
This is really only an option for benign moles because of the way the procedure is performed. A knife is used to shave the mole off layer by layer until it is level with the skin and as such any part of the mole under the skin is left there. So if you had a cancerous mole this method would be ineffective because the cancer can continue to grow and spread underneath the skin. Cauterization is used here is in the previous method.
