Mohs Surgery for High-Risk or Recurrent Skin Cancers

At First Capitol Surgical Dermatology in St. Charles, MO, we specialize in advanced surgical treatment for skin cancers that require a high level of precision and long-term control. When skin cancer appears in sensitive areas, shows aggressive features, or returns after prior treatment, standard excision may not provide the reliability patients need. In these situations, Mohs surgery offers a highly effective, tissue-sparing approach designed specifically for high-risk or recurrent skin cancers.

What is Mohs Surgery?

Mohs surgery is a precise surgical technique that removes skin cancer while preserving as much healthy tissue as possible. Unlike traditional excision, which removes a predetermined margin of skin, Mohs surgery involves removing the cancer in thin layers and examining each layer under a microscope in real time. We repeat this process until we confirm that no cancer cells remain. This method allows us to precisely track and eliminate cancer while minimizing unnecessary removal of surrounding skin.

Why Mohs Surgery Is Used for High-Risk Skin Cancers

High-risk skin cancers often behave differently than low-risk lesions. They may grow more aggressively, extend deeper into the skin, or spread beyond what appears visible on the surface. Cancers located on the face, ears, scalp, hands, feet, or genital area also qualify as high-risk due to functional and cosmetic concerns. Mohs surgery allows us to fully evaluate cancer margins during the procedure, which significantly reduces the risk of leaving cancer cells behind.

Mohs Surgery for Recurrent Skin Cancer

When a skin cancer returns after previous treatment, it often grows in unpredictable patterns beneath the skin. Scar tissue from prior surgery can also make margins difficult to define. Mohs surgery is especially valuable in these cases because it traces the exact extent of the cancer, even when it extends beyond the original site. This approach provides the highest cure rates for recurrent basal cell and squamous cell carcinomas.

What to Expect During the Procedure

We perform Mohs surgery as an outpatient procedure using local anesthesia. Patients remain awake and comfortable throughout the process. After each layer removal, patients wait while we examine the tissue. Once we confirm complete cancer removal, we focus on repairing the surgical site in a way that supports healing and cosmetic outcome.

Focused Care for Complex Skin Cancers

Our goal with Mohs surgery is complete cancer removal with the lowest possible chance of recurrence. This precision-based approach makes it the gold standard for treating high-risk and recurrent skin cancers.
