About me

Dr. Steven Seyedin is a radiation oncologist who cares for patients with genitourinary cancers (those of the reproductive and urinary systems). His treatment expertise includes prostate, kidney, bladder and testicular cancer.

His research focuses on integrating advanced technologies, such as stereotactic body radiation therapy (which allows precise delivery of high radiation doses), with other targeted therapies in order to improve patients' chances of beating genitourinary cancers. He enjoys collaborating with other UCSF researchers to usher new treatments from the laboratory to the clinic and offering his patients clinical trials with cutting-edge treatment. His work has been published in JAMA Oncology, Frontiers in Oncology, and the International Journal of Radiation Oncology, Biology, and Physics.

He earned his medical degree at the David Geffen School of Medicine at UCLA. He completed a residency in radiation oncology at the University of Iowa.

While he is a San Francisco Bay Area native, he has lived in five states over the past 15 years and was thrilled to come back home to provide care to his community. When he isn't in the clinic or at his office conducting research, he can often be found on a tennis court or spending time with his nephews.
