Understanding Mohs Surgery: What to Expect
Mohs micrographic surgery is the most effective technique for treating many types of skin cancer, offering cure rates up to 99%. Unlike standard excision, Mohs surgery involves removing skin cancer layer by layer, examining each under a microscope during the procedure.
Before Your Surgery
Prepare by arranging transportation home, wearing comfortable clothing, and eating a good breakfast. Continue taking all your regular medications without any changes. Bring a complete list of all medications and supplements you take to your appointment.
During the Procedure
The area is numbed with local anesthesia. Dr. Kaplan removes a thin layer of tissue, which is then processed and examined under a microscope. If cancer cells remain at the margins, another layer is removed from the precise area where cancer was found. This process repeats until all margins are clear.
After Surgery
Most patients experience minimal pain managed with over-the-counter medication. You'll receive detailed wound care instructions. Stitches are typically removed within 7-14 days depending on the surgical site. Most patients return to normal activities within a few days.
Why Choose Mohs
Mohs surgery is the gold standard because it offers the highest cure rate while preserving the maximum amount of healthy tissue, which is essential for areas like the face where cosmetic outcomes matter.
