How Is Mohs Surgery Different from Standard Excision?
- Posted on: Mar 15 2026
When treating skin cancer, the method used to remove the tumor matters just as much as early detection. Patients are often told they need either Mohs surgery or standard excision, but they may not understand the differences between these two approaches.
At American Dermatology Associates in Sarasota, FL, board-certified dermatologist Dr. Jennifer Plush wants her patients to fully understand their options so they can feel confident in their treatment plan and long-term skin health.
What Is Standard Excision?
Standard excision is a commonly used technique to remove skin cancer. During this procedure, the visible tumor is removed along with a margin of surrounding healthy tissue. The excised tissue is then sent to a laboratory, where it is analyzed to determine whether cancer cells remain at the edges. Results are typically available days later.
If cancer cells are found at the margins, an additional procedure may be needed to remove remaining tissue. While standard excision is effective for many low-risk skin cancers, it does not allow for immediate confirmation that all cancer has been removed at the time of surgery.
What Makes Mohs Surgery Different?
Mohs surgery is a specialized technique designed to remove skin cancer layer by layer while preserving as much healthy tissue as possible. After each layer is removed, it is examined under a microscope on the same day. This process continues until no cancer cells are detected.
Because Mohs surgery evaluates 100 percent of the surgical margins in real time, it offers the highest level of precision. This approach is especially valuable for skin cancers located on the face, ears, hands, or other areas where tissue preservation is critical. It is also often recommended for recurrent or aggressive skin cancers.
Key Differences Between Mohs Surgery and Standard Excision
The most significant difference lies in how margins are evaluated. Standard excision examines a small sample of the margins, while Mohs surgery examines the entire margin. Mohs surgery also allows for immediate confirmation of complete cancer removal, reducing the likelihood of additional procedures.
From a cosmetic standpoint, Mohs surgery often results in smaller wounds, which may support more favorable healing and reconstruction outcomes.
Choosing the Right Treatment Approach
Not all skin cancers require Mohs surgery. The appropriate treatment depends on factors such as cancer type, size, location, and whether it has been previously treated. Dr. Plush carefully evaluates each case and recommends the approach that balances effectiveness, safety, and long-term skin health.
