Everything you need to know your risk — in one place.
A curated, trustworthy library: a featured disease each month, patient guides from PatientResource, the current NCCN guidelines, and the talks and symposia where the science moves.
This month: Early-Onset Colorectal Cancer.
Each month Preempt features one disease and gathers the best of what exists around it — so the people who need it are not searching alone.
Early-Onset Colorectal Cancer
Colorectal cancer is rising fastest in adults under 50 — and screening guidelines have only just begun to catch up. Average-risk screening now starts at 45, and earlier for anyone with a family history or a known genetic variant. This month's collection brings together what to know, what to ask, and what to do next.

Each month, a new disease moves to the front. PatientResource shares its content for that month, alongside the relevant NCCN guidelines and the season's talks and symposia. Past months stay in the library.

Preempt's library is educational. It is not a diagnosis and does not replace a conversation with your clinician. Guidelines change — always confirm current guidance with a qualified professional, and talk with a clinician or genetic counselor about what your personal risk means for you.
