Why is the procedure called Mohs?

Mohs is named after its inventor, Dr. Frederic Mohs, who first described the technique in 1941. He originally used fixed stained tissue and patients were frequently required to spend more than one day for successful treatment. This unique technique made it possible to examine horizontal pieces of tissue from the deepest portion of the specimen while at the same time visualizing the outside edges of the tumor in the same block of tissue is unique.

Where can I have Mohs surgery? How long does Mohs surgery take?

Mohs micrographic surgery is usually performed in an outpatient setting, such as in a doctor's office, using local anesthetic (lidocaine). Sometimes the procedure may be performed in an outpatient surgical center with the assistance of an anesthesiologist. Rarely, it is performed in an inpatient hospital setting.

You are generally in the medical office for several hours on the day of your Mohs procedure. Depending on the size and depth of the skin cancer, more than a single level may be required to achieve clearance. MMS requires your patience and your doctor's careful effort and skill. It is not always possible to predict ahead of time how many hours your specific procedure will take. Most patients leave their day's schedule open to allow for adequate time to complete their Mohs procedures.
