Mohs Surgery Process

Mohs skin cancer surgery is one of the most effective treatments for most types of skin cancer. During the procedure, the surgeon removes the cancer, analyzes the area to be sure all cancer is removed, and then repairs the wound. Here is how the process works:

Step 1

Skin cancers often extend beyond their visible borders. It is these extensions that cause the tumors to recur if not completely removed.

Step 2

Using advanced surgical techniques, the surgeon removes the visible portion of the tumor.

Step 3

A thin layer of skin is then removed and mapped to track exactly where each small portion of tissue originated.

Step 4

The surgeon uses a microscope to examine the undersurfaces and edges of the tissue to search for evidence of remaining cancer.

Step 5

If the surgeon finds cancer cells under the microscope, he or she marks their location on the “map” and returns to the patient to remove another deep layer of skin. When there is no longer any evidence of cancer the removal process stops.

Mohs surgery removes only tissue containing cancer, which ensures that the maximum amount of healthy tissue is kept intact. Once complete, the surgeon will discuss reconstruction options, if necessary, and post-operative care.
