Mohs micrographic surgery involves removing a skin cancer one layer at a time and examining these layers under a microscope immediately after they are removed. This procedure allows for a close examination of each layer of skin to detect cancer cells. It also allows a minimal amount of tissue to be removed while making sure that all the cancer cells are removed.
A local anesthetic is injected into the skin before the surgery. Your doctor then begins to remove the skin cancer and a small amount of healthy tissue, one layer of skin at a time. Each tissue layer is prepared and examined under the microscope for cancer cells. Surgery is complete when no more cancer cells are detected.
Recovery may take 2 to 4 weeks, depending on the extent of surgery.
