What is Mohs Micrographic Surgery?

Mohs Micrographic Surgery is a precise surgical technique used to treat skin cancer. It involves removing cancerous tissues layer by layer while preserving as much healthy tissue as possible. Each layer is examined under a microscope to ensure all cancer cells are removed.

How Does Mohs Micrographic Surgery Work?

Stage 1
Mark Identified Skin Cancer

The identified skin cancer is marked. Local anesthetic is given via a small injection. Once the area is numb and sterilized, the Mohs surgeon will proceed to remove the tissue. This is then mapped and sent for processing in the laboratory. Whilst awaiting the results of the results of Stage 1, the wound is dressed, and the patient may wait in the waiting area.

Stage 2
Getting Results

Once the results are back, the Mohs surgeon will read the slides to see if there are any remaining skin cancer cells. If there are, the patient will undergo removal of another skin layer only at the involved segment of the wound (under local anaesthesia). The tissue will be mapped and sent to the laboratory for processing.

Stage 3 onwards (if required)
Rinse And Repeat

These stages are repeated until all tissue margins are clear. Once the margin is clear, the wound will be reconstructed. The Mohs surgeon will discuss with you options of reconstruction which includes skin flaps or grafts.

What types of skin cancer can be treated with Mohs Micrographic Surgery?

Mohs Micrographic Surgery is primarily used for basal cell carcinoma and squamous cell carcinoma. It is also effective for other skin cancers in areas where preserving healthy tissue is crucial, such as the face.
How long does the Mohs Micrographic Surgery procedure take?

The procedure can take several hours, as each layer of tissue is removed and analyzed on-site until clear margins are achieved. The exact duration depends on the cancer's size, location, and depth.
What should I expect during the recovery period?

Recovery is usually quick, but it can vary based on the cancer's size and location. Patients may experience some discomfort, swelling, or bruising. Following your surgeon's post-operative care instructions is essential for optimal healing.
Are there any risks or complications associated with Mohs Micrographic Surgery?

As with any surgery, there are potential risks, such as bleeding, infection, scarring and recurrence. Your Mohs Micrographic surgeon will discuss these with you.
How should I prepare for Mohs Micrographic Surgery

Patients should discuss any medications they are taking with their surgeon and follow specific pre-operative instructions provided. It is recommended to arrange transportation home after the procedure due to potential temporary discomfort or numbness.
What are the benefits of Mohs Micrographic Surgery compared to other skin cancer treatments?

Mohs Micrographic Surgery offers a high cure rate and minimizes the removal of healthy tissue, which leads to better cosmetic outcomes. It is ideal for cancers with a high risk of recurrence or those located in cosmetically sensitive areas.
