A doctor called a radiation oncologist will oversee your radiation therapy treatments at Mary Bird Perkins Cancer Center. This doctor will work with the other members of the radiation therapy team to develop your treatment plan and ensure that each treatment is accurately given. Your radiation oncologist will also monitor your progress and adjust the treatment as necessary to make sure the radiation is hitting its target while minimizing side effects. Before, during and after your radiation therapy treatments, your radiation oncologist will work closely with your other cancer doctors, such as your medical oncologist and/or surgeon, to maximize the radiation’s effectiveness.
Radiation oncologists have completed at least four years of college, four years of medical school, one year of general medical training and three to four years of residency or specialty training in radiation oncology. They have extensive training in cancer medicine and the safe use of radiation to treat disease. All of Mary Bird Perkins’ radiation oncologists are board certified by the American Board of Radiology.

Dr. Fields’ education began with a BS in Mechanical Engineering and an MS in Applied Mechanics. After attending medical school at Thomas Jefferson, he trained in Internal Medicine residency with board certification. He obtained further medical training at M. D. Anderson Cancer Center as a resident and fellow in Radiation Oncology, and as chief resident. He then stayed at Anderson for another four and one-half years on staff as assistant professor specializing in head and neck malignancies.
In addition to his clinical work at MBPCC, he is an adjunct professor with the Louisiana State University Department of Physics and Astronomy’s medical physics program.
A native of New Jersey, Dr. Fields has been with Mary Bird Perkins Cancer Center since 1986.
