Dr. Carter is a board-certified radiation oncologist who has been practicing at Rocky Mountain Cancer Centers since 2001. His areas of expertise include targeted radiation therapy, stereotactic radiosurgery (SRS), stereotactic ablative radiotherapy, stereotactic body radiation therapy (SBRT), intensity-modulated radiation therapy (IMRT), image guided radiotherapy (IGRT), 3-D conformal radiation therapy, and accelerated partial breast irradiation (ABPI). He treats a wide variety of cancers, with a special interest in breast cancers, head and neck cancers, lung cancers, prostate cancer, skin cancers, and oligometastases. He believes in a compassionate, patient-centered approach. He enjoys educating his patients about their diagnoses so they can participate in a shared decision-making process about their cancer treatment plan, which he feels is an important part of optimizing his patients’ outcomes.

Dr. Carter participates in many tumor boards, where he collaborates with other cancer specialists including surgeons, radiologists, pathologists, and medical oncologists. This allows him to provide a comprehensive, multi-disciplinary approach to his cancer treatment recommendations. Dr. Carter has served as principal investigator for many Phase II and Phase III studies, including studies specific to breast cancer, lung cancer, head and neck cancers, and metastatic cancers (liver, oligometastases). Dr. Carter's publications have been cited by other researchers over 2000 times.

Along with his radiation oncology partners, Dr. Carter was instrumental in the development of accelerated partial breast irradiation, maintaining one of the largest databases in the world for intensity modulated accelerated partial breast irradiation, in which small breast tumors can be treated over just one week. He emphasizes the importance of participating in clinical research trials when appropriate to ensure his patients are receiving the most up-to-date, cutting-edge treatment for their disease.
