Mohs Surgery vs. Excision: Understanding the Difference in Results

When skin cancer is diagnosed, choosing the right treatment approach is an important part of protecting both your health and your appearance. Mohs surgery and standard surgical excision are two of the most common treatments used to remove skin cancer, but they work very differently. At Scott Sanders Dermatology in New City, NY, patients receive guidance on which option offers the strongest outcome based on cancer type, size, location, and personal goals.

How Mohs Surgery Works

The Mohs surgical technique is a type of skin cancer procedure that removes cancerous cells with very high precision. A specialist in skin disease called a dermatologist performs Mohs surgery by removing small amounts (called layers) of tissue containing the cancerous cells, examining each layer under a microscope to see if any cancer cells remain. The Mohs technique continues until there are no remaining cancer cells in the area, ensuring that only cancerous tissue is taken.

Because Mohs surgery targets the cancerous cells directly through real-time inspection, it has a very high success rate for clearing skin cancers while preserving as much healthy skin around the affected area as possible. This is especially important for skin cancer procedures performed in visible areas (like the facial area or hands) or function-sensitive areas (like lips, etc.).

How Surgical Excision Works

The surgical excision method also involves removing the cancerous tissue, but the technique for this form of surgery is different than Mohs surgery. In a standard surgical excision method, the dermatologist removes both the cancerous tumor and a specified margin of surrounding healthy skin. This excised tissue is then sent to an outside pathology laboratory for analysis; however, it can take several days to receive any results.

Surgical excision is a well-established, effective method for treating many types of skin cancer and is often recommended for growths located on the trunk, arms, legs, or other areas where preserving skin is less challenging. It may also be preferred for certain tumor types or when Mohs surgery is not necessary.

When Each Treatment Is Recommended

The choice between Mohs surgery and excision depends on the size, depth, and characteristics of the cancer. Mohs surgery is commonly used for basal cell carcinoma or squamous cell carcinoma in high-risk locations, skin cancers with unclear borders, recurring tumors, or growths on the face, scalp, neck, or hands. Surgical excision may be recommended for tumors in areas with more available skin, low-risk basal cell or squamous cell carcinomas, and certain early melanomas. A detailed evaluation helps determine which approach offers the best cure rate and cosmetic outcome.
