Dr. Mandel is fortunate to have an ongoing practice that includes a variety of areas of surgical oncology, including the breast and the gastrointestinal tract among others.  He is gratified to be given the opportunity to care for so many individuals with cancer and to participate in their journey along with his talented colleagues at the Carol G.
