What is the goal of Mohs surgery?

The goal of Mohs surgery is to remove all of the skin cancer. To be more specific, the surgeon will want the skin around where the cancer used to be, called the margins, to be cancer-free. That is why you may hear your surgeon say that he or she wants to do as many stages or passes as are needed to “clear the margins”. Learn more about how well Mohs works to remove skin cancer.
