Surgical oncology is the branch of surgery applied to oncology. It focuses on the surgical management of tumors especially cancerous tumors. As one of several modalities in the management of cancer, the specialty of surgical oncology has evolved in steps similar to medical oncology like pharmacotherapy for cancer, which grew out of hematology, and radiation oncology which grew out of radiology. The Ewing Society known today as the Society of Surgical Oncology was started by surgeons interested in promoting the field of oncology. Complex General Surgical Oncology was ratified by a specialty Board certification in 2011 from the American Board of Surgery. The proliferation of cancer centers will continue to popularize the field as will developments in minimally invasive techniques, palliative surgery, and neo-adjuvant treatments.
