Get to know Radiation Oncologist Dr. Sylvia Zubyk, who serves patients in San Antonio, Texas.

As a female radiation oncologist and native of South Texas, Dr. Zubyk brings an element of expertise and dedication to both her patients and the START Center for Cancer Care.

Located in San Antonio, Texas, the START Center for Cancer Care is known internationally for its tradition of excellence and its contributions to the advancement toward a cancer cure. This is due to the combined efforts of a large team of cancer specialists dedicated to the most advanced, complete, and effective care. The surgeons, medical oncologists, radiation oncologists, and gynecologic surgical oncologists have the combined knowledge, skill, and capabilities that patients can depend on and trust. But most of all, the cancer doctors are caring people who understand what it means to face cancer and who have committed themselves to helping a patient or their loved one win the fight.

Having been serving the San Antonio area since 2004, Dr. Zubyk received her Bachelor of Science degree in Biology from Texas A&M University, and her medical degree from the University of Texas Medical Branch at Galveston. She then went on to study radiation oncology at Mary Imogene Bassett Hospital in Cooperstown, New York, and at Duke University Medical Center in Durham, North Carolina. She completed her residency in radiation oncology at the University of Texas Health Science Center at San Antonio.

After graduation, she remained on faculty within the Department of Radiation Oncology at the University of Texas Health Science Center at San Antonio, overseeing the breast cancer service. Since then, Dr. Zubyk has continued to dedicate herself to the care and treatment of women with breast cancer. She offers her expertise in all areas of breast cancer, including external beam radiotherapy and IMRT of the breast.

Licensed by the state of Texas, the doctor is board-certified in diagnostic radiology by the American Board of Radiology (ABR). The mission of the ABR is to serve patients, the public, and the medical profession by certifying that its diplomates have acquired, demonstrated, and maintained a requisite standard of knowledge, skill, and understanding essential to the safe and competent practice of diagnostic radiology, radiation oncology, and medical physics.

Radiation oncology is a medical specialty that involves the controlled use of radiation to treat cancer. It is one of the three primary specialties, the other two being surgical and medical oncology, involved in the treatment of cancer. A radiation oncologist is a specialist physician who uses ionizing radiation in the treatment of cancer.

In honor of her expertise, Dr. Zubyk has received several awards in her young career, including “Top 40 under 40 professionals in San Antonio” by the San Antonio Business Journal (2006), Patients’ Choice Award (2015), On-Time Doctor Award (2015), and Compassionate Doctor Recognition (2015). She has also been named in the “Top 100 Physicians in San Antonio” by San Antonio Magazine.
