Mohs Surgery Staff | Knott Street Dermatology | MOHS Micrographic Surgery | Portland OR

MOHS STAFF

Mohs micrographic surgery is a specialized, highly effective technique for the removal of skin cancer. The procedure was developed in the 1930s by Dr. Frederic Mohs and is now practiced throughout the world. Unlike other skin cancer treatments, Mohs surgery allows tissue to be removed in stages and examined under the microscope to facilitate clearance of abnormal cells while you wait. Due to the methodical manner in which the tissue is extracted and examined, Mohs surgery is recognized as the skin cancer treatment with the highest reported cure rate.
