Mohs Micrographic Surgery

Let's Talk Skin Cancer Treatment

What is Mohs micrographic surgery?

Mohs micrographic surgery is a specialized technique developed to remove certain types of skin cancer. It was developed by Dr. Frederick Mohs at the University of Wisconsin in the 1930’s and has been refined over the following decades. It is an outpatient procedure performed with local anesthesia, which helps eliminate the risks associated with general anesthesia. It is very safe and well-tolerated by patients.

After the tumor and surrounding skin have been completely numbed, the Mohs surgeon removes the visible portion of the tumor or biopsy site and small margins surrounding it. This “layer” of tissue is then taken to our laboratory, where it is processed and turned into slides. The Mohs surgeon examines the slides under the microscope to determine if there is any remaining skin cancer at the edges or base. If no cancer cells are seen, the Mohs surgeon repairs the wound with stitches (or allows the wound to heal if stitches are not needed). If any cancer cells remain, then additional tissue is removed in the area where the skin cancer was seen. This process is repeated as many times as necessary until the tumor has been completely removed.
