The Practice in Numbers: Updated Mohs Surgery Data (July 2026)
The Numbers, as of July 2026
- 5,000+ Mohs procedures performed by Dr. Kaplan over his career
- 1,000+ of them as primary surgeon during his ACMS-accredited fellowship in Miami
- 100% of the surgical margin is examined under the microscope in Mohs surgery, versus roughly 1-2% in standard excision
- Up to 99% cure for primary BCC and about 94% for recurrent tumors, per the published literature
- 30-45 minutes per removal-and-examination cycle, with 1-3 cycles needed in most cases
Why Publish Numbers?
When a patient chooses a Mohs surgeon, they usually encounter general phrases: "extensive experience", "unique expertise", "thousands of satisfied patients". It is hard to base a decision on those. This page does something different: it presents the numbers themselves, explains what each one means (and what it does not mean), and points to external sources where they can be verified.
The page is updated quarterly. The date of the last update appears at the top.
“A patient choosing a surgeon should not have to settle for 'extensive experience'. Precise numbers, verifiable against external professional bodies, are the basic form of respect owed to someone entrusting you with their face.”
Experience in Numbers
Over 5,000 Mohs procedures. This is the cumulative number of procedures Dr. Kaplan has performed, as of July 2026. Behind the number stands variety: primary and recurrent tumors, complex anatomic sites (nose, eyelids, ears, lips), and a full range of reconstruction techniques, from direct closure to local flaps and skin grafts. The figure also appears on Dr. Kaplan's official profile in the practitioner directory of the European Society for Micrographic Surgery (source 2 below).
Over 1,000 procedures as primary surgeon during fellowship. During his American College of Mohs Surgery accredited fellowship year at Skin and Cancer Associates / Mount Sinai Medical Center, Miami Beach (2022-2023), Dr. Kaplan performed over 1,000 Mohs procedures as primary surgeon under supervision. The ACMS fellowship is the field's structured, supervised training pathway, and Dr. Kaplan's Fellow profile appears in the College's official directory (source 1 below).
The Numbers of the Technique Itself
100% of the margin is examined. In Mohs surgery, the tissue is sectioned in a way that allows microscopic examination of the entire margin, both peripheral and deep. In standard excision, where tissue is sent to an external laboratory, only representative slices are examined, typically covering about 1-2% of the margin surface. That structural difference explains the gap in cure rates.
Up to 99% cure for primary BCC. According to the field's most cited literature, the long-term cure rate of Mohs surgery for primary BCC reaches about 99%, and about 94% for recurrent tumors (sources 3-4). These are the technique's figures from the medical research, not any single clinic's personal statistics.
30-45 minutes per cycle, 1-3 cycles in most cases. Each round of layer removal, on-site laboratory processing, and microscopic examination takes about 30-45 minutes, with the patient waiting comfortably between rounds. Most procedures require one to three rounds for complete removal.
What the Numbers Do Not Say
This needs saying just as clearly: no number on this page is a guarantee of outcome for your individual case. Every tumor differs in type, size, location, and history, and every patient differs in health. Cure rates come from studies of large populations; they describe the technique, not a single case. At the consultation, Dr. Kaplan explains what the data means for your specific situation, including the alternatives.
How the Numbers Are Collected and When They Update
The procedure count is based on the case log Dr. Kaplan maintains routinely, in line with ACMS standards. The technique data comes from the professional literature cited in the sources. The page is updated quarterly, and the date of the last update appears at its top.
