Dr. Sean Cavanaugh joined Cancer Treatment Centers of America® (CTCA) in Newnan, Georgia, to maintain his focus on the patient’s well-being as a top priority. "At CTCA, the difference is teamwork," says Dr. Cavanaugh, who is Chief of Radiation Oncology. “Here, the physicians truly work together on the same team to help our patients."

After joining CTCA in 2012, Dr. Cavanaugh launched the Brachytherapy Program at our Atlanta-area hospital and helped grow the Radiation Oncology Department. He has chaired the hospital's Prostate Center for Advanced Oncology and Prostate steering committee. Dr. Cavanaugh also graduated from the hospital's Physician Leadership Program.

Dr. Cavanaugh earned his medical degree from Texas Tech University Health Sciences Center in Lubbock. He then completed an internship in General Pediatrics at University of Texas Health Science Center at San Antonio, where he also finished the B. Leonard Holman Pathway Residency in Radiation Oncology.

Prior to CTCA, Dr. Cavanaugh worked in private practice for seven years in both Texas and Georgia. He is an experienced radiosurgeon, operating on both extracranial and intracranial malignancies. Dr. Cavanaugh regularly performs high-dose rate and low-dose rate brachytherapy, as well as all aspects of highly conformal external beam radiation therapy.

Certified by the American Board of Radiology, Dr. Cavanaugh is also a member of the American College of Radiology and the International Society for Radiosurgery. He has been published in numerous journals, including Urology, Prostate Cancer, American Journal of Brachytherapy, The International Journal of Radiation Oncology, Biology and Physics, and Technology in Cancer Research and Treatment.

"I take the fight against cancer very personally,” says Dr. Cavanaugh, whose brother and father are both cancer survivors. "It is my privilege to care for my patients in the most advanced and compassionate manner possible."

In 2011, Dr. Cavanaugh was honored with a Compassionate Doctor Certification from Patient’s Choice. He also received Georgia’s Favorite Physicians Award in 2009, 2010 and 2011. Dr. Cavanaugh received the Patients' Choice Award and the On-Time Physician Award from Vitals.com in 2014.
