Rebecca Swender

Dr. Swender is an oncologist at Seattle Grace Hospital, and specifically, Izzie's oncologist.

Career
Dr. Swender is the authoritarian and impartial view of Izzie's cancer treatment, being a doctor that's had no prior relationship to Izzie, taking charge of her treatment and having all surgeons, including the Chief, Dr. Shepherd and Dr. Bailey report to her regarding Izzie's treatment. She will also be the doctor administering Izzie's chemotherapy and radiotherapy as well as overseeing all surgeries on her, as shown when she begins to second guess Dr. Shepherd in his surgery on Izzie, unsettling and distracting Derek on his first surgery back, which was one of Izzie's surgeries. However, he does find his feet again and quickly silences Dr. Swender.
