Mohs Micrographic Surgery
State-of-the-art treatment for skin cancer
A skin cancer diagnosis can be devastating—but our qualified physicians are well-versed in treatment options that can help. We understand that while skin cancer may be common, dealing with it isn’t easy. Mohs Surgery can minimize the damage done to healthy cells during treatment so healing can start as soon as possible.
What is Mohs surgery?
Mohs Micrographic Surgery is a precise surgical technique used to treat difficult and recurrent skin cancers. A specially fellowship-trained dermatologist takes on the role of surgeon, pathologist and reconstructive surgeon getting to the root of skin cancer by combining surgical removal with immediate microscopic examination of the tumor and underlying diseased tissue. The process allows the Mohs surgeon to see beyond the visible disease and to prescisely identify and remove the entire tumor while preserving as much healthy tissue as possible.
What makes Mohs surgery different?
Moms Micrographic Surgery is an improvement from standard surgery. It involves the removal of not only the visible cancer but a small margin of surrounding cancer tissues all at once. This allows for all the cancer cells to be removed at the time of surgery and helps to decrease the chances of cancer progression.
When should you consider Mohs surgery?
Of all treatment for skin cancer, Mohs Micrographic Surgery offers the highest cure rate, up to 99% based on data for treating basal and squamous cell carcinomas. The procedure aims to remove all cancer cells including the hard-to-see “roots” and “nests” of cells that grow in unpredictable areas. Mohs surgery can successfully remove all cancer cells and eliminate the risk of re-growth or recurrence of the tumor.

- Cancer in difficult-to-heal areas such as the lower legs
- Cancer in young patients (< 40 years old) or immunocompromised patients (organ transplant or leukemia/lymphoma patients)
- Cancer forms a complicated root system without clearly defined margins
- Cancer was previously treated but has recurred
What can you expect during surgery?
During Mohs surgery, thin layers of skin are progressively removed and examined until only cancer-free tissue remains. The procedure is done on an outpatient basis and can take anywhere from a few hours to a whole day to complete. A local anesthetic will be injected and the surgeon will use a scalpel to remove the visible portion of the cancer. That layer is then examined for cancer cells so the surgeon can determine the best way to proceed. This process continues until only healthy tissue remains.
Surgeons you can count on
Our surgeons specialize in both dermatology and pathology. With their extensive knowledge of the skin and unique pathological skills, they are able to remove only diseased tissue, preserving healthy tissue and minimizing the cosmetic impact of surgery. Our doctors are Fellowship-trained Mohs Surgeons. They undergo a one or two-year fellowship program under the supervision of an experienced American College of Mohs Surgery (ACMS) approved Mohs surgeon.
