By using detailed mapping techniques, the Mohs surgeon can pinpoint areas that are otherwise invisible to the naked eye.  Therefore, even the smallest root to the cancer can be removed.  The result is #1 removal of as little as normal skin as possible and #2 the highest possibility of curing the cancer even when other methods of treatment have failed. 

The Mohs technique is the treatment of choice for many cancers of the face and other critical body areas.
