Dr. Amar Rewari on Nothing Left Unsaid: Cancer, Fear, and What Patients Really Need

Dr. Amar Rewari joined the Nothing Left Unsaid podcast for a wide-ranging conversation about what cancer care actually looks like from the other side of the exam room — the part patients rarely hear about.

Dr. Rewari, Chief of Radiation Oncology at Luminis Health, opened by describing what a patient needs in the moments after a diagnosis. In his experience, it isn't information. Most people aren't absorbing much of what's said in that first conversation, and what matters most is simply knowing they aren't alone. From there, he explained, every patient is different: some want statistics, some want a plan, some want hope, and some just need room to cry, pray, or be angry.

The conversation moved through several of the topics that define his day-to-day work:

• Cancer myths and online fear. Dr. Rewari described the shift from "Dr. Google" to "Dr. ChatGPT," and addressed common misconceptions — that sugar feeds cancer, that radiation causes severe burns, and that a diagnosis is automatically terminal. He noted that many early-stage cancers now carry cure rates above 90%, and that his job is less about correcting ignorance than about addressing fear.

• Prior authorization and access. Drawing on his health policy background, he explained how insurance approval delays create real anxiety for cancer patients, and how transportation, childcare, and caregiving obligations can quietly determine whether someone completes treatment.

• Rising cancer rates in younger adults. He discussed the increase in colorectal cancer among younger patients and the range of possible contributing factors, while being clear about what the research does and doesn't yet show.

• Prevention that's actually supported by evidence. Don't smoke, maintain a healthy weight, exercise, stay current on screenings, get the HPV vaccine, and use sunscreen — rather than worrying about dryer sheets, seed oils, and microplastics.

• Career, ambition, and fulfillment. Dr. Rewari also reflected on his path from medicine to an MBA and investment banking and back again, and on what leadership roles have cost him in time.

He closed on what cancer has taught him about control — that it's largely an illusion, and that hope isn't the belief that everything will be fine, but the practice of finding meaning regardless of what comes next.
