Mohs Micrographic Surgery is a highly specialized, state-of-the-art technique used for the treatment of complex skin cancers. This procedure was first developed in the 1930’s by Dr. Frederick Mohs, a professor of surgery at the University of Wisconsin. Mohs micrographic surgery is distinct from routine surgical excision. With the Mohs technique, surgically removed tissue is carefully mapped, color-coded, and thoroughly examined microscopically at the time of surgery. During this process, 100% of tissue margins are evaluated to ensure that the tumor is completely removed prior to repair of the skin defect. Mohs micrographic surgery therefore results in the highest cure rate for complex skin cancers while minimizing the removal of normal tissue.
