What is Mohs surgery? 

Mohs micrographic surgery is a safe and highly effective technique whereby skin cancers are removed under complete microscopic control. The procedure is named after Dr. Frederic Mohs who developed this specialized technique in the 1930’s. In Mohs surgery, a thin layer of skin is removed around the visible cancer. Detailed maps are then drawn of the area, and 100% of the tissue margin is examined under the microscope to be sure that all of the cancer and its roots are gone. If any cancer remains, the exact area of involvement is sampled, and the entire process is repeated until the cancer is totally removed.
