What is Mohs Surgery?

Mohs surgery, also known as Mohs micrographic surgery, is a highly specialized surgical technique used to treat certain types of skin cancer. It is named after Dr. Frederic Mohs, who developed the procedure in the 1930s.

This surgical procedure is primarily used to remove basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), which are the most common types of skin cancer. Mohs surgery is particularly effective in treating skin cancers located in areas where preserving healthy tissue is crucial, such as the face, ears, nose, and hands.

The Mohs Surgery Procedure

Mohs surgery is performed in several stages, combining surgical removal of the cancerous tissue with immediate microscopic examination. The procedure involves the following steps:

Tumor Removal: The surgeon first numbs the area with a local anesthetic. Then, using a scalpel, the visible tumor is carefully excised.

Tissue Mapping: The surgeon maps the removed tissue and marks it for precise identification during microscopic examination.

Tissue Examination: The excised tissue is processed and divided into thin sections, which are then stained and examined under a microscope. This step allows the surgeon to determine if any cancer cells remain.

Tumor Margin Evaluation: If cancer cells are detected at the margins, the surgeon precisely removes additional tissue from the corresponding area. This process is repeated until no cancer cells are found at the margins.

Wound Closure: Once the cancer is completely removed, the surgeon discusses the best method for wound closure. This may involve sutures, skin grafts, or other reconstructive techniques.

Advantages of Mohs Surgery

Mohs surgery offers several advantages over traditional surgical methods for treating skin cancer:

• High Cure Rates: Mohs surgery has the highest cure rates among all skin cancer treatment options, with cure rates exceeding 99% for certain types of skin cancer.
• Tissue Preservation: By precisely removing only cancerous tissue, Mohs surgery minimizes the removal of healthy tissue, resulting in smaller scars and better cosmetic outcomes.
• Real-Time Examination: The immediate microscopic examination of tissue allows the surgeon to accurately identify and remove cancer cells, reducing the need for additional surgeries.
• Minimal Discomfort: The procedure is performed under local anesthesia, minimizing discomfort during and after the surgery.

It is important to note that Mohs surgery is not suitable for all types of skin cancer. Your dermatologist or surgeon will determine if you are a candidate for this procedure based on various factors, including the type, size, and location of the skin cancer.

If you have been diagnosed with skin cancer, consulting with a qualified dermatologist or surgeon experienced in Mohs surgery can help you explore the most appropriate treatment options for your specific case.
