Benjamin Cahan, M.D.

In medicine, we can combine leading-edge science, ingenuity and innovation with warmth and kindness to try to help the patient and their loved ones as best we can. Benjamin Cahan, M.D., is a radiation oncologist and assistant clinical professor in the Department of Radiation Oncology at City of Hope | South Pasadena. Dr. Cahan specializes in all forms of radiation treatment including emerging treatments, such as image guided radiotherapy, stereotactic radiosurgery and stereotactic body radiation therapy. Dr. Cahan earned his medical degree from the University of California Los Angeles (UCLA) David Geffen School of Medicine, from which he graduated with Alpha Omega Alpha honors. His training continued with an internship at UCLA-Olive View Medical Center. He then joined City of Hope in 2012 as a resident in radiation oncology. In 2015, he was named chief resident, a position he held until joining our faculty full time at City of Hope | South Pasadena in 2016. Dr. Cahan always puts his patients first. His research is focused on the impact of therapies on patients' quality of life. His approach to clinical practice focuses on providing both excellent medical treatment and strong support and reassurance, to reduce his patients’ anxiety. He fully subscribes to City of Hope's “body and soul” credo. In his words: “We must care for our patients' entire selves, and not just their disease.”
