Mohs surgeons treat skin cancer using a precise, layer-by-layer method. They train in dermatology and surgery, and they specialize in removing cancerous tissue. If you have a diagnosis on your face or hands, you may meet one soon, and knowing the steps ahead helps you be prepared for your appointment. This is what to expect while getting skin cancer treatment:
Local Anesthesia
Your visit typically starts with local anesthesia at the treatment site. The surgeon cleans the area, marks the tumor, and numbs the skin with an injection. Since the medication works quickly, you stay awake during the whole procedure. You feel a brief pinch, but the spot goes numb within minutes.
Local anesthesia means general sedation is typically not needed. You sit upright in a chair, and the team monitors your comfort. While the numbing holds, Mohs surgeons prepare the first layer of tissue for removal.
Visible Tumor Removal
Next, the surgeon removes the visible portion of the tumor. This first pass targets the cancer you and the doctor see on the surface. Since the area is numb, you feel pressure rather than pain. The surgeon works carefully and removes a thin layer of skin.
Here is what the team does during this stage:
- Maps the removed tissue with a diagram
- Marks the edges with colored dye
- Dresses the wound while you wait
After this step, you typically rest in a waiting area. The work pauses, and the tissue moves to the on-site lab. You stay comfortable while the analysis begins.
Removed Tissue Analysis
The removed tissue now goes under the microscope. A technician freezes the sample, slices it thin, and stains it for review. Since the lab is on-site, results arrive promptly, typically within one or two hours. The surgeon examines every edge for remaining cancer cells.
This analysis guides the next decision. If the margins look clear, your treatment ends that day. While you wait, you may read, rest, or check your phone. The careful review separates Mohs surgery from other removal methods.
The wait time varies by case. Some samples take longer to process, and complex tumors need extra study. You stay in the clinic during this period, and the team updates you on progress.
Additional Stages
Sometimes the first layer still shows cancer cells at the edges. When this happens, the surgeon numbs the area again and removes another thin layer. Since each pass targets only affected tissue, healthy skin stays intact. The team repeats the lab analysis after every stage.
Patients may need one or two stages, though some need more. The process continues until the margins read clear. While this adds time to your visit, it limits the size of the wound. You may spend several hours at the clinic on procedure day. Use these steps to start your search:
- Ask your dermatologist for a referral.
- Check that the surgeon holds Mohs fellowship training.
- Confirm the clinic has an on-site lab.
