How Does Mohs Surgery Work?


First, you receive local anesthesia around the area of the tumor. Once the anesthetic has taken effect, our ACMS surgeon removes the visible tumor, along with a thin layer of surrounding tissue. This takes only a few minutes.


While the patient waits, the pathologist examines the tissue specimen for cancer cells, and that examination informs the surgeon where to removed tissue next. The surgeon performing the procedure is also the pathologist reading the specimen slides.


If their is evidence of cancer around the outer edges of the removed tissue, another layer of tissue is taken from the area where the cancer was detected. Your surgeon repeats these steps until all samples are free of cancer.
