Free · open-source · no sign-up
A second opinion on cancer treatment — free, cited, and open.
Enter a case and OpenOnco lays out two treatment plans side by side — a standard option and a more aggressive one — with a source you can open under every line. Built on NCCN, ESMO and CIViC. Pick your path below.
Rules-first, not an LLM — no drug or dose is ever invented. Patient data stays in your browser. A qualified clinician is always the final authority.
Open-data inputs: CIViC (CC0), ClinicalTrials.gov, PubMed, DailyMed/openFDA and NCCN/ESMO/EHA/BSH guidelines. No LLM chooses treatment — plans are rules-first with YAML provenance (CHARTER §11).
