Mohs Surgery Procedure Step by Step


A step-by-step explanation of the Mohs Micrographic Surgery procedure

The Mohs Micrographic Surgery procedure is rather simple: skin cancer surgeon Dr. Joseph Sedrak removes the observable cancerous growth, carefully exams the removed tissue to ensure the cancerous sells are fully surrounded by healthy skin cells, then repairs the wound. However, to perform this surgery, expert training and expertise is required. In practice the complex nuances of this process can take years to perfect. A Mohs surgeon like Dr. Sedrak requires a deft touch to ensure they’re prepared to handle any situation they may encounter. This page describes the steps Dr. Sedrak follows for each Mohs surgical procedure.

Mohs skin cancer surgery is the most effective treatment for most types of skin cancer. To learn about the expertise and experience of our team, start by reading about Dr. Sedrak biography.

Step 1

The roots of a skin cancer may extend beyond the visible portion of the tumor. If these roots are not removed, the cancer will recur. A surgery starts with skin cancer surgeon Dr. Sedrak conducting a special examination of the visible lesion and planning what tissue to remove. The patient then receives local anesthesia, and the Mohs surgery begins.

Step 2

Dr. Sedrak starts by removing the visible portion of the tumor using careful surgical techniques. The surgical excision is designed to be extract as much of the tumor as possible without affecting the surrounding healthy tissue.

Step 3

Dr. Sedrak next removes a deeper layer of skin and divides it into sections. With the help of technicians, Dr. Sedrak then color-codes each of these sections with dyes and makes reference marks on the skin to show the source of the sections. A map of the surgical site is then drawn to track exactly where each small portion of tissue originated.

Step 4

In a laboratory, Dr. Sedrak uses a microscope to examine the undersurface and edges of each section of tissue in search of evidence of remaining cancer.

Step 5

If Dr. Sedrak finds cancer cells under the microscope, he marks their location on the “map” and returns to the patient to remove another deeper layer of skin — but only from precisely where the cancer cells originated. This method ensures that the Mohs surgery extracts the least amount of healthy tissue and results in the smallest scar possible.

Step 6

The removal process stops when there is no longer any evidence of cancer in the surgical site. Because Mohs surgery removes only tissue containing cancer, it ensures that the maximum amount of healthy tissue is kept intact.

At this point, the Dr. Sedrak discusses reconstruction options, should they be required, and then post-operative care. Mohs surgery recovery tends to be easily manageable because of the use of local anesthesia and the careful surgical techniques.
