Mohs Micrographic Surgery for Skin Cancer

If you have been diagnosed with skin cancer, Allegheny Health Network in Pittsburgh offers Mohs micrographic surgery, a highly specialized treatment with the highest cure rate for skin cancer.

What is Mohs Micrographic Surgery?

Mohs surgery is named in honor of Dr. Frederic E. Mohs, the physician who developed the technique in the 1930s. It has since been continuously refined. The Mohs surgery technique is unique in that it combines surgical removal of the cancer with immediate microscopic examination of the tissue. This allows the surgeon to remove only cancerous skin and preserve as much healthy skin as possible. For these reasons, Mohs surgery has the highest cure rate of all skin cancer treatment methods, and also creates the smallest possible surgical defect, allowing for a better cosmetic outcome.

What are the advantages of Mohs?

  • Highest cure rate for skin cancer. The cure rate after treatment of a primary tumor is 98-99%, and cure rate after treatment of a recurrent tumor (one that was previously treated) is 95%.
  • After removing the tumor, the tissue is processed and the surgeon examines the entire margin under the microscope. If more tumor remains, the surgeon uses the map to determine where further tissue needs to be removed. This process is repeated until the entire margin is clear of tumor, ensuring removal of all skin cancer and minimizing removal of healthy tissue.
  • Complete removal of the skin cancer and reconstruction the same day. When necessary, coordinated care with other specialists such as oculoplastics, plastic surgery or radiation oncology is readily available within Allegheny Health Network.
  • The procedure is done under local anesthesia, eliminating the risks of intravenous sedation or general anesthesia.
  • It is a cost effective form of skin cancer removal given the high cure rates and low complication rates.

 

Can my skin cancer be treated with Mohs?

 

Mohs micrographic surgery is primarily used to treat basal and squamous cell cancers, but can also be used to treat less common tumors, including dermatofibrosarcoma protuberans and others. Indications for Mohs surgery include:

  • A cancer in a "high risk" or cosmetically sensitive area (scalp, face, ears, neck, hands, feet, genitalia)
  • A cancer that was previously treated and recurred
  • A large cancer
  • A cancer with ill-defined edges
  • A cancer that is growing quickly
