Oncology specialists collect medical histories and perform physical evaluations in addition to basic administrative duties, such as maintaining records, coordinating with other medical personnel, and managing the work of staff. They also perform a wide variety of diagnostic procedures to ascertain the condition of tissues and to detect cancer. Diagnostic procedures include scanning techniques, such as x-ray and magnetic resonance imaging, as well as surgical operations and biopsies.
Treatment options include chemotherapy, radiation therapy, and the surgical removal of cancer. Oncology professionals may also perform procedures to treat regions of the body affected by cancer treatment. For instance, a gynecologic oncologist may perform surgery to a patient's gastrointestinal tract that has been adversely affected by treatment.
