A generation should not have to inherit its diagnosis.
Preempt is the international 501(c)(3) for risk-based cancer prevention — building the world where every adult knows their risk and acts on it before disease begins.
Preventable before the fact — not only curable after it.
The fastest-growing cancer demographic in the world is the one we are least prepared for: working-age adults. Colorectal cancer in their thirties. Breast cancer in their forties. Pancreatic, gastric, kidney — every solid tumor is now appearing earlier than the screening guidelines anticipate.
Preempt is built on a single premise: this is preventable. Risk-based knowledge, applied early, ends most of these diagnoses before they begin.
Our goal is a clear one — one billion adults knowing their cancer risk by 2030.
The elements of Preempt.
Preempt brings three forces together: the science, the coalition, and a way to find what works.
The international academic society advancing the science of risk-based prevention — researchers, clinicians, and academic medical centers.
