When facing a diagnosis of skin cancer, particularly on sensitive areas like the face, patients naturally want the most effective treatment with the best cosmetic outcome. One procedure frequently discussed in this context is Mohs micrographic surgery. A common and important question arises: can dermatologists perform this specialized surgery? The answer is a definitive yes. In fact, dermatologists who complete additional, rigorous fellowship training are the specialists who most commonly perform Mohs surgery.
What is Mohs Surgery?
Mohs micrographic surgery is a precise technique for removing certain types of skin cancer. It is distinguished by its method of examining 100% of the surgical margins during the procedure. The surgeon removes the visible tumor and then maps, divides, and microscopically examines the tissue layer by layer. This process continues until no cancer cells are detected, ensuring complete removal while sparing as much healthy tissue as possible. According to data from the American College of Mohs Surgery, this technique offers the highest reported cure rates for common skin cancers like basal cell carcinoma and squamous cell carcinoma, often exceeding 99% for new cancers.
The Role of Dermatologists in Mohs Surgery
Dermatology is the medical specialty dedicated to the diagnosis and treatment of skin, hair, and nail conditions, which includes skin cancer. The path to becoming a Mohs surgeon begins with becoming a board-certified dermatologist. Following dermatology residency, a physician must complete a dedicated ACGME-accredited fellowship in Mohs micrographic surgery and dermatologic oncology. This extra year (or more) of training focuses intensely on advanced surgical techniques, complex reconstruction, and the intricate microscopic pathology interpretation required for the procedure.
Therefore, the dermatologists who perform Mohs surgery are subspecialists with extensive, focused training. They are uniquely positioned to manage the entire spectrum of skin cancer care, from initial detection and biopsy to the surgical removal and final reconstruction of the wound.
When is Mohs Surgery Typically Recommended?
Mohs surgery is not necessary for every skin cancer. Dermatologists recommend it based on specific clinical factors that suggest a higher risk of recurrence or a need for tissue preservation. Common indications include:
- Cancers located in cosmetically or functionally critical areas (e.g., nose, eyelids, ears, lips, fingers).
- Skin cancers that are large in size.
- Cancers that have recurred after previous treatment.
- Tumors with aggressive growth patterns under the microscope.
- Cancers with poorly defined borders.
Your dermatologist or a Mohs surgeon will evaluate your specific diagnosis, the cancer's characteristics, and your overall health to determine if Mohs surgery is the most appropriate treatment option for you.
What to Expect from the Mohs Surgery Process
If Mohs surgery is recommended, understanding the process can help alleviate concerns. The procedure is typically performed in an outpatient setting under local anesthesia. On the day of surgery, the Mohs surgeon will numb the area, remove the visible tumor, and begin the cycle of mapping and microscopic examination. This cycle may be repeated several times until the margins are clear. Because the tissue processing and analysis happen on-site, the entire process can take several hours, though much of that time is spent waiting for the lab work. Once the cancer is fully removed, the surgeon will discuss the best method for repairing the wound, which may range from simple healing to a more complex reconstruction.
Consulting with a Specialist
If you have been diagnosed with a skin cancer for which Mohs surgery might be beneficial, the next step is to consult with a qualified specialist. You can seek a board-certified dermatologist who has completed an accredited fellowship in Mohs micrographic surgery. These specialists can provide a comprehensive evaluation, discuss all treatment options, and explain the potential benefits and expectations of the Mohs procedure for your individual case.
Early detection and appropriate treatment remain the cornerstones of successful skin cancer management. Regular skin self-exams and annual professional skin checks with a dermatologist are vital for prevention and early intervention. For personalized medical advice regarding skin cancer diagnosis or treatment, always consult a board-certified dermatologist.
