If you have been told you need Mohs skin cancer surgery, you likely have questions. Your provider answers the most common ones in plain language. Mohs surgery treats certain skin cancers with precision, and it has a high cure rate.
What Is Mohs Surgery?
Mohs skin cancer surgery is a precise treatment for skin cancer. A specially trained surgeon removes cancer one thin layer at a time, and each layer is examined under a microscope. Because the surgeon checks the tissue right away, only cancerous cells are removed. Healthy skin is preserved. This approach falls under surgical dermatology, but it differs from general dermatology, which often handles diagnosis and basic care.
It is often used for cancers on the face, neck, or hands. The technique works well for basal cell and squamous cell carcinomas, the most common skin cancers. It is also helpful when a cancer has unclear borders or returns after earlier treatment. Because the surgeon maps each layer, the method offers a top cure rate. You get results during the same visit, so you do not wait days for a lab report. This precision matters most in areas where saving healthy tissue protects function and appearance.
What Happens During the Procedure?
The procedure happens in stages, and it is done in one visit. You stay awake the entire time. You can move and rest between layers. Most visits last a few hours, though complex cases can take longer. You may bring a book or use your phone while the tissue is reviewed. Steps include:
- Your surgeon numbs the area with a local anesthetic.
- A thin layer of tissue is removed and examined in the lab.
- If cancer remains, another layer is taken until no cancer cells are found.
- The waiting time between layers depends on how the lab processes each sample.
- Once the area is clear, your surgeon repairs the wound based on its size and location.
Small wounds may heal on their own, while larger ones need stitches or a skin graft. Your surgeon explains the repair plan before starting, so you know what to expect. Each session will differ.
What Does Recovery Involve?
Recovery is usually straightforward. Most people return to light activity within a day or two. You will receive wound care instructions, and following them closely helps healing. Keep the area clean, avoid heavy lifting, and watch for signs of infection. Some swelling or bruising is normal, and it typically fades within a week. You may have mild discomfort, and an over-the-counter pain reliever often eases it. Change your bandages as directed, because clean dressings lower the chance of complications. Healing time varies by person, and it depends on the wound size and its location. Your dermatology team schedules follow-up visits so they can monitor healing and check for any new concerns. They may also remove stitches at the right time, and they will review your results with you. Apply sunscreen daily, and limit direct sun exposure during healing.
