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 and Medical Director of our Prostate Center. “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.
