Mohs Surgery
Before, During, & After

Mohs surgery is a state-of-the-art procedure that removes the skin on a lesion layer by layer. Each piece of removed (excised) tissue is examined under a microscope on the same day as surgery, and these tissue layers are progressively excised until no tumor cells are seen.

The goal of this type of surgery is to remove all of the malignant cells and as little normal tissue as possible. This procedure is also performed on an outpatient basis, under a local anesthesia.

When Mohs Surgery Is Used

The types of cancer tumors most likely to be treated by Mohs micrographic surgery are:

  • Tumors in cosmetically sensitive or functionally critical areas, such as around the eyes, nose, lips, scalp, fingers, toes, or genitals.
  • Tumors that are large, aggressive, or growing rapidly.
  • Tumors that are recurrent.
  • Tumors that have ill-defined edges.

Mohs surgery is also often used with recurring tumors.

Advantages of Mohs Micrographic Surgery

The advantages of using this procedure are:

  • It offers the highest potential cure rate—up to 99%—for skin cancer;
  • By removing the least amount of tissue, it maximizes the likelihood for preserving function and it also offers superior cosmetic results; and
  • It causes fewer risks with anesthesia because it uses a local rather than a general anesthesia.
