What is Mohs Surgery?

Mohs surgery is currently one of the most precise and effective medical procedure to get rid of skin cancer. The procedure involves cutting out the infected area and then some. The infected patch of skin is then frozen and cut into sections of skin that are then stained with special dyes. The frozen pieces of skin are further examined under the microscope in which a tumor map is drawn by our Mohs surgeon. 

The layers of skin that are infected are gradually removed until they are clear of any malignant cells. If more cancer cells or “roots” are seen under the microscope, then another skin layer is removed and again examined. This procedure is repeated throughout the surgery. By removing only the tissue where cancer is known to be present, the technique combines a very high cure rate with good preservation of normal skin. Once the cancer has been fully removed, our Mohs surgeon looks at the best method of covering the open wound. 

Mohs surgery removes as much of the malignant cells as possible, or completely gets rid of them. Our doctor doing Mohs surgery can verify the skin cancer has been removed from the person. Usually one treatment is necessary to get rid of the skin cancer. In recent years, there has been medical advances that allow Mohs surgeons to treat Melanoma cells and have resulted in specially made stains that can identify these cells.

History of Mohs Micrographic Surgery

Mohs is not an acronym but it is the name for the founder of the surgery technique. Mohs micrographic surgery was invented by Frederic E. Mohs, MD. When he was in school studying medicine during the late 1920’s he was mentored by a professor who specialized in the preparation of frozen tissue and producing microscopic slides. Using what he had learned about microscopic performance, he was able to map out cancer around nerves, blood vessels and any bones

When he examined a cancer he would extract it with a thin disc of tissue so he could completely infiltrate the cancer. After finishing school he began his practice in 1936 and successfully treated his first patient with a squamous cell cancer. He spent four years refining his practice and perfecting his procedure. Throughout time the Mohs Micrographic surgery was improved with color-codded mapping and a more detailed microscopic examination.
