What Happens During Mohs Surgery?
Because Mohs Surgery is performed with local anesthesia, it is an out-patient surgery that is typically performed in the doctor’s office. The surgeon will begin by removing layers of the skin and then putting it on a slide to examine under a microscope. If they see cancer in that layer of tissue, they will remove another layer and examine that layer under the microscope. This will continue until there are no cancerous cells on the layer that has been removed. This process ensures that no cancerous cells are left behind to grow and spread. When the doctor is satisfied that he has removed all of the cancerous cells, he will do any reconstruction, skin grafts, or stitches that are necessary before sending you home. The wound is usually covered and pressurized for 24 hours to promote clotting and lower the risk of blood loss. You will be instructed to keep the surgical site dry for at least one day to reduce the chance of infection. It is important to avoid heavy lifting and physical activities for 1 or 2 days. The doctor will give you complete instructions for caring for your wound before you leave his office.
