Dr. Steve Braunstein is a radiation oncologist who cares for both adult and pediatric patients. He specializes in treating brain and spinal tumors, sarcomas, lymphoma and pediatric cancers. He also provides palliative radiotherapy to reduce symptoms in patients with advanced cancer. His expertise encompasses a number of technologies that use radiation as therapy, with a special focus on intraoperative radiotherapy and radiosurgery – using targeted high-dose radiation to destroy tumors, either as an alternative to surgical procedures or in combination with them.

Braunstein's primary areas of research include improving radiation planning and treatment through the use of both gene marker analysis and advanced imaging technologies. He also studies how to improve the coordination, timing and delivery of health care that involves a variety of disciplines, including symptom management and cancer specialties.

After earning his medical degree as well as a doctorate in biomedical sciences at New York University School of Medicine, Braunstein completed a residency in radiation oncology at UCSF.

    Dr. Braunstein is a jewel. He is very caring and obviously a radiation oncology expert. I feel very blessed to have him as my doctor. He listens and explains things very clearly, and his knowledge is wide and deep, and his experience is vast. My 2 radiation courses with him have been very successful. I feel very confident entrusting my treatment to him.

    Alex (Dr. Braunstein's resident) and Dr. Braunstein were amazing. He went through my MRI slides and answered all my questions patiently and completely. Alex put me at ease; he is a great listener and very respectful. Dr. Braunstein, as Alex before, respectfully and patiently listened and answered all my questions completely. Utilizing Telehealth was easy and perfect for this follow-up visit.

    I was completely satisfied at how the provider explained and went through the process of how they treat patients with regards to their particular case. I got a strong sense that they were the best option out there by far and that they were going to provide me with the best care possible. Yes, I would definitely recommend them to someone seeking cancer treatment.

    I don't choose doctors based on kindness but it was a wonderful bonus that the doc was so supportive and kind. Even more knowledgeable on the most minute details of my many questions. Made a difficult situation much easier.
