Get to Know Me

I am a practicing radiation oncologist with a focus on clinical trials for genitourinary cancer, which includes prostate cancer, bladder cancer, and kidney cancer.

My goal is to use the latest imaging and radiotherapy technologies to improve treatment results for patients. I see patients at Memorial Hospital and the David H. Koch Center for Cancer Care at MSK.

Recent advancements in radiotherapy have improved our ability to precisely target tumors, so that treatments are now effective as well as minimally invasive. The use of real-time imaging and adaptive treatment planning also plays an important role in delivering personalized care. I believe that every person deserves a treatment plan tailored to their unique needs and situations. I emphasize precision and adaptability in radiation therapy. This approach not only enhances the treatment results but also reduces side effects, which improves the patient experience.

When patients first meet with me, they often express concerns about the safety and effectiveness of new treatment technologies. I take the time to thoroughly explain the procedures and benefits, making sure that they feel informed and confident in their treatment plan. My goal is to provide the latest care in a warm and supportive environment.

I also serve as the Director of the Genitourinary Program in the Department of Radiation Oncology. In this role, I oversee the development and use of the latest treatments and clinical trials so that our team is a leader in radiation therapy.

MSK is terrific and sets the bar for other institutions.

Mar 31, 2025

Dr. Nagar is in an extremely good position. I always enjoy speaking with him. He's clear, he's polite, and he's extremely professional. Regarding his switch to Sloan Kettering, I have found the experience to be somewhat difficult in that Sloan Kettering is far more bureaucratic than Cornell was, and the situation up to the point where I spoke with Dr. Nagar was unnecessarily confusing and confused, although it was not his fault. That would be the comment I would make. Thank you.

Mar 31, 2025

I have full trust in my care by Dr. Nagar and his understanding of my illness.

Mar 31, 2025

Dr. Nagar was very kind, respectful and knowledgeable. He took the time to answer my questions and made me feel better prepared to move forward with my decision.
