Skin Cancer & Mohs Surgery


Mohs surgery is a highly advanced treatment for skin cancer. Our surgeons have had extensive Fellowship Training beyond dermatology residency. Using the Mohs technique, the physician serves as oncologic surgeon, pathologist, and reconstructive surgeon.

This tissue-sparing technique of Mohs Surgery offers several advantages over other treatments.

1. Allows for potentially smaller scars because it minimizes the removal of normal, healthy skin.

2. Results in the highest cure rate of any treatments for skin cancer – up to 99% for basal cell carcinoma and squamous cell carcinoma.

3. Reduces the risk of infection and eliminates the side effects of general anesthesia because it is performed under local anesthesia as an outpatient, office-based procedure.

Are you at risk for skin cancer?

Why Choose a Fellowship-Trained Mohs Surgeon?


Mohs surgeons are required to complete an intensive one or two year post-residency training program which requires them to participate in at least 500 Mohs micrographic surgery cases under the supervision of an experienced ACMS-approved Mohs Surgeon. They receive extensive experience in the removal and microscopic analysis of a variety of skin cancers, and in the complex reconstruction of surgical defects.

The Mohs surgery technique of skin cancer removal was developed to achieve definitive treatment of skin cancer with minimal damage to, and limited removal of, healthy skin. Unlike excisions—a standard dermatological procedure involving removal of the visible tumor along with a wide, arbitrary margin of normal skin—Mohs precisely excises only affected tissue, layer-by-layer, until the tumor is extracted in its entirety.

Whereas excisions are sent off-site to a pathologist to be examined at a later date, Mohs emphasizes same-day results and a single on-site procedure. Mohs surgery is considered the Gold Standard of skin cancer treatment, and is a highly advanced procedure and should only be performed by surgeons who specialize in the technique. When performed by a Fellowship-Trained Mohs Surgeon, like those at our practice, patients can expect and have come to rely on us for the definitive diagnosis and removal of skin cancers.

The Mohs procedure begins by removing the visible skin cancer and processing the sample in our on-site Mohs laboratory, where it is examined under the microscope by your surgeon. After evaluating the tissue, the Mohs surgeon draws a map to show where, if anywhere, residual skin cancer remains. Using this map, subsequent layers of cancer-containing tissue can then be removed while sparing the normal healthy tissue around it. This process is repeated until the entire skin cancer, including any roots, is removed.

An excision is a minor surgical procedure performed on an outpatient basis in our office. The procedure involves the complete removal of a lesion. The excised tissue is sent to an outside laboratory for processing. Laboratory processing ensures all the margins are clear and the lesion has been completely removed.

The actual procedure is as follows:

  • Once the area is located, marked and cleaned, a local anesthetic (usually Lidocaine or Xylocaine) will be injected into the surgical area. This is the only part of the procedure that will cause discomfort. There will be the sensation of stinging or burning. We inject very slowly to minimize the discomfort as much as possible.
  • Once the area is numb, the lesion as well as the surrounding tissue will be removed with a scalpel.
  • The small amount of bleeding will be stopped with a machine that coagulates the blood vessels.
  • The wound will be closed with sutures and a dressing will be applied.
  • The tissue will be sent to an outside laboratory for processing to ensure all margins are clear. You will be informed of the laboratory results 7-10 days from the date of your surgery.
