At Cancer Treatment Centers of America, experts join together to analyze and discuss each case, and decisions are made as a team. It is a different approach to healthcare, and I wanted to be a part of it.

After joining CTCA in 2012, Dr. Cavanaugh launched the Brachytherapy Program at our Atlanta-area hospital and helped grow the Radiation Oncology Department.

Patient Ratings
The patient ratings and comments on this page are obtained from an external Press Ganey® outpatient survey provided to all eligible CTCA patients within one to two weeks of their treatment occurrence. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five- star rating. In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, or do not relate to the patient's experience with the doctor involved including comments directed at hospital COVID-19 policies and procedures. As a result, the comments are the views and opinions of the patients surveyed and are not endorsed by, and may not necessarily reflect the opinion of, CTCA.
