Patients would carry their full cancer history, scans and test results in a standard digital bundle they control and can hand to any doctor anywhere.
Patients see multiple providers across systems and countries; records do not follow them. A FHIR-based, patient-held record (International Patient Summary plus mCODE bundle, images via DICOMweb links) stored in a patient-controlled vault would make the patient the integration point. Apple Health records, the EU patient summary, and Blue Button show pieces exist; oncology-specific completeness (staging, regimens, genomics, imaging) is missing.
Every source this page cites, grouped by who published it. Grouping is read from the web address, not assigned by hand.
