Nagourney Cancer Institute

Nagourney Cancer Institute At Nagourney Cancer Institute (formerly Rational Therapeutics), we believe that every cancer patient deserves the right treatment the first time, every time.

Your cancer is as unique as your fingerprint. Drugs that work for one patient may not work for another, even if they carry exactly the same diagnosis. We offer testing that measures how your cancer cells will respond to drugs BEFORE you receive them. This testing helps select the most effective and least toxic drug regimen for your cancer. Our founder and medical director, Dr. Robert Nagourney, ha

s been internationally recognized as a pioneer in cancer research and personalized cancer treatment for over 20 years. He has worked 20+ years refining a process that examines the biology of your tumor to identify the most effective, least toxic treatment for YOU. Our patients have been shown to be twice as likely on average to respond to a cancer treatment when chosen in our laboratory compared with standard treatment protocols. With these results, you and your doctors are equipped with personalized information to make the most informed decision to treat YOUR cancer. Truly Personalized Cancer Care.

What if everything we’ve been taught about cancer is only part of the story?
In this powerful episode of Metabolic Matters, Dr. Nasha Winters sits down with pioneering oncologist Dr. Robert Nagourney to explore how his revolutionary approach, based on functional profiling and metabolomics, is transforming cancer care as we know it.

For decades, Dr. Nagourney has challenged protocol-driven medicine by focusing on what actually works for each patient: testing how their cancer responds to treatment, in real time, using live tissue. Now, he's leading the charge in metabolomics, developing breakthrough blood-based diagnostics that detect cancer before it appears—and give us a new way to think about prevention.

This is a must-watch conversation for anyone impacted by cancer, working in medicine, or curious about the future of metabolic health.
