Benjamin Cahan , M.D.

Radiation Oncologist
Assistant Clinical Professor, Department of Radiation Oncology

“In medicine, we can combine cutting 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., treats patients at our South Pasadena practice. He is trained in all areas of radiation oncology including the latest advances in image-guided radiotherapy, brachytherapy, 3D conformal radiotherapy and 4D computed tomography simulation.

Dr. Cahan is a “home-grown” member of our City of Hope family. He joined us as a Resident in 2012 after receiving his medical degree and interning at UCLA.

Whether in the lab or the examination room, Dr. Cahan always puts his patients first. He has focused his research on the impact of different therapies on patients' quality of life. In his clinical practice he strives to calm patients' fears, and offer support and reassurance. 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.”
