Mohs Micrographic Surgery for Skin Cancer: The Most Effective Treatment for Basal & Squamous Cell Carcinoma
What Is Mohs Micrographic Surgery?
Mohs micrographic surgery is a specialized skin cancer treatment designed to completely remove cancer while preserving as much healthy skin as possible. It is considered the gold standard treatment for many basal cell and squamous cell skin cancers, particularly those on the face or other cosmetically sensitive areas.
Unlike standard excision, Mohs surgery allows the surgeon to examine 100% of the surgical margins during the procedure, ensuring that all cancer cells are removed before reconstruction begins.
Why Mohs Surgery Has the Highest Cure Rates
Mohs surgery achieves the highest cure rates of any skin cancer treatment because it combines precise surgical removal with immediate microscopic analysis.
Typical cure rates include:
- Up to 99% for new basal cell carcinomas
- Up to 95–97% for recurrent tumors
This level of precision significantly reduces the risk of recurrence while minimizing the amount of tissue removed.
How Mohs Surgery Works (Step-by-Step)
- Cancer Removal – The visible tumor is removed under local anesthesia.
- Microscopic Mapping – The tissue is processed and examined on-site by the Mohs surgeon.
- Targeted Additional Stages – Only areas with remaining cancer are re-treated.
- Clear Margins Confirmed – Surgery ends once all cancer is removed.
- Same-Day Reconstruction – Repair is performed immediately when possible.
This process ensures complete cancer removal in a single visit for most patients.
When Is Mohs Surgery Recommended?
Mohs surgery is commonly recommended for skin cancers that:
- Are located on the face, ears, nose, lips, eyelids, scalp, hands, or feet
- Have recurred after prior treatment
- Are large, aggressive, or poorly defined
- Occur in immunocompromised patients
- Require tissue conservation for cosmetic or functional reasons
Your dermatologist determines whether Mohs surgery is appropriate based on pathology, location, and individual risk factors.
What to Expect on the Day of Surgery
Most Mohs procedures are completed in one outpatient visit. The length of the appointment varies depending on the number of stages required.
Patients typically:
- Remain awake with local anesthesia
- Experience minimal discomfort
- Wait comfortably while tissue is examined
- Leave the same day with wound care instructions
Recovery and Healing After Mohs Surgery
Recovery depends on the size and location of the surgery, but most patients:
- Resume normal activities within a few days
- Experience minimal pain
- Heal with excellent cosmetic results when properly reconstructed
Detailed aftercare instructions are provided to promote optimal healing and scar appearance.
