Radiation oncologist April Vassantachart, M.D., knows that it is a privilege to support and guide patients through their cancer journey. As a physician, Dr. Vassantachartbelieves that her relationship with her patients requires a special connection that involves listening and learning on both ends to produce an individualized plan that meets the unique needs of each patient. A Southern California native, she was drawn to City of Hope because of its reputation for high-quality, innovative cancer care focused on treating the whole person.
The ability to combine her knowledge of physics and technology with medicine to provide precise, noninvasive oncologic care is what inspired Dr. Vassantachart to become a radiation oncologist. She has published an article in the International Journal of Radiation Oncology, Biology and Physics that evaluates the effects of health literacy on understanding radiation therapy, with the goal of improving shared decision-making with diverse populations. Dr. Vassantachart has also written a book chapter on the treatment of brain metastases in Intracranial Stereotactic Radiosurgery.
In her free time, Dr. Vassantachart’s hobbies include cultivating exotic house plants, playing pickleball, hiking the California mountain ranges and exploring the food scene in Los Angeles.
