Mohs Micrographic Surgery

Mohs micrographic surgery (Mohs) is an advanced treatment procedure for skin cancer that offers the highest potential for recovery. A state-of-the-art procedure, Mohs allows specially trained dermatologists to see beyond the visible disease and precisely identify and remove the entire tumor, leaving healthy tissue unharmed.

Mohs is most often used to treat two of the most common forms of skin cancer: basal cell carcinoma and squamous cell carcinoma. According to the American College of Mohs Surgery, the cure rate is the highest of all treatments for skin cancer—up to 95 percent—even if other forms of treatment have failed.  This procedure, the most exact and precise method of tumor removal, minimizes the chance of regrowth and lessens the potential for scarring or disfigurement. 

The Mohs Procedure

The Mohs process includes a specific sequence of surgery and pathological investigation. Mohs surgeons examine the removed tissue for evidence of extended cancer roots. 

Once the obvious tumor is removed, the Mohs surgeon will:

  • Remove an additional thin layer of tissue from the tumor site
  • Create a "map" or drawing of the removed tissue to be used as a guide to the precise location of any remaining cancer cells
  • Microscopically examine the removed tissue to check for evidence of remaining cancer cells 

If any of the sections contain cancer cells, the Mohs surgeon will return to the specific area of the tumor site as indicated by the map, remove another thin layer of tissue from the specific area where cancer cells were detected, and microscopically examine the newly removed tissue for additional cancer cells. If microscopic analysis still shows evidence of disease, the process continues layer by layer until the cancer is completely gone. 

This selective removal of only diseased tissue allows preservation of much of the surrounding normal tissue. Because this systematic microscopic search reveals the roots of the skin cancer, Mohs offers the highest chance for complete removal of the cancer while sparing the normal tissue; cure rates exceed 99 percent for new cancers and 95 percent for recurrent cancers.
