The Era of Personalized Cancer Prevention and Early Detection has Begun.

Conventional cancer screening was designed for populations. PreOncology™ was built for the individual.

PreOncology delivers the first medical-grade, oncologist-led cancer prevention and early detection program built to identify cancer at Stage Alpha, so that cure, not lifelong treatment, becomes the expected outcome.

The System Was Designed to Be Reactive

Every year, cancers are diagnosed at an advanced stage, when cure is often no longer possible. Conventional screening was not designed to prevent that. It was designed to detect the most common cancers in the general population, at a single point in time, without regard for individual biology or risk.

PreOncology was founded by oncologists who spent decades on the wrong side of that timeline. We built what the field was missing.

Detect Cancer at Stage Alpha

The PreOncology Program™ delivers continuous, personalized cancer prevention calibrated to each member’s individual biology and risk profile, combining computational modeling, molecular diagnostics, and precision screening under the direct oversight of board-certified medical oncologists.

The program is designed to detect cancer at Stage Alpha, the earliest point at which a confident, actionable determination can be made for that individual, so that cure, not lifelong treatment, becomes the expected outcome.

A New Standard of Care

The PreOncology Program is designed for two groups of people: the physicians who refer it, and the members it serves. For both, it replaces reactive, population-based screening with continuous, personalized cancer prevention built around the individual.

Every day a cancer is found late is a day the system failed someone. We have spent our careers on the receiving end of that failure. As oncologists, we wanted our expertise to reach patients earlier — at the point where prevention and very early detection is still possible. By partnering with primary care physicians, we finally can.

Transform Population-Based Screening into Individual Surveillance

The PreOncology Program opens to concierge and direct primary care physicians this summer.
