Care Philosophy

This content was provided by Dr. Ahn "Philosophy of Care:

No two cancer patients are exactly alike, so the need and ability to highly customize radiation treatment requires disease-specific training and extensive experience. Minimizing the long-term side-effects of today's advanced treatments is also a major consideration. Dealing with the unique challenges inherent in each patient's social situation, individual goals of care, and tumor characteristics keeps me excited about my work as a member of the dedicated and experienced team of physicians, nurses, technicians and physicists at MedStar Georgetown. "
