Mohs Surgery (or Mohs Micrographic Surgery) is a technique used to treat skin cancer. The purpose of the procedure is to completely remove all of the cancer while leaving normal skin tissue alone. Mohs Surgery is a highly specialized surgical technique where the surgeon examines all tissue removed for evidence of cancer cells.

What happens during the procedure?

When the tumor appears to be removed the surgeon follows a unique method of confirming it is excised completely.

1. The surgeon will remove a thin layer of tissue from the tumor site
2. The surgeon then creates a "map" of the tissue to be used as a guide for locating any remaining cancer cells
3. The surgeon microscopically examines all of the excised tissue to confirm that the margins of the tumor are clear

If any cancer cells are found in the sections of removed tissue, the Mohs surgeon will then return to the specific area of residual tumor (as noted by the tissue map) and remove another thin layer of tissue. This new tissue will also be examined for cancer cells. This process will be repeated, layer by layer, until the cancer tissue is completely removed.

Once the cancer is confirmed to be removed, the surgeon will determine the best method of closing the wound. A small wound may be allowed to heal on its own or it will be closed with stitches. Mohs surgeons are trained in reconstruction techniques and will select the best option available to minimize scarring.

Will there be a scar?

Yes, every surgical procedure leaves a scar. However, Mohs surgery tends to minimize scarring since only the tumor tissue is removed and healthy tissue is left behind.

What is the advantage to Mohs Surgery?

This has a very high cure rate for skin cancer because the surgeon confirms through microscopic analysis that the entire tumor is removed during the procedure. It traces the cancer to its root through the mapping process and excises it.

How long does the procedure take?

It will take a few hours and extensive tumors may take longer.

How should a patient prepare for this procedure?

Get a good nights sleep, wash hair and face on the day of the surgery, eat a normal breakfast, wear clothing that buttons in the front and do not wear jewelry or makeup if surgery is to be performed on the face.
