Dermatologist explains Mohs surgery as a treatment for skin cancer

What is Mohs surgery?

Mohs surgery was developed in 1938 by Frederic E. Mohs, a general surgeon. It is a microscopically controlled procedure to treat skin cancer. Layers of tissue are removed and examined separately to search for cancer cells. If found, the next layer of skin tissue is removed. The process continues until the cells are clear. Mohs surgery allows the surgeon to only remove the necessary amount of tissue.

Mohs surgery is generally used to treat skin cancer on the face, hands, feet, or genitals. In these areas, tissue preservation is crucial. Mohs surgeries have a high cure rate.

The Mohs process

There are four basic steps to a Mohs surgery:

  • Surgical removal
  • Mapping, freezing, cutting, and staining the tissue
  • Microscopic analysis
  • Possible reconstruction of the area

A Mohs surgery is generally performed under local anesthesia. A small scalpel is used to remove the visible cancer with minimal margins. General excisions of skin cancers remove a 4 to 6 mm margin. Moh’s margins are 1 to 1.5 mm, meaning less healthy tissue is excised. As each layer of tissue is removed, it is examined, with the surgeon acting as the pathologist. The top three steps are repeated as needed. Once the margins are clear, surgical closure or reconstruction can be performed.
