Exposome fingerprints for early cancers

Researchers are moving from associations to chemical forensics by scanning blood for tens of thousands of compounds and matching 'exposome' signatures that appear more often in early‑onset cancer patients. Paired with zebrafish exposed to known and suspected carcinogens, this can validate which chemicals plausibly drive tumors in younger cohorts. — Turning diffuse environmental debates into measurable chemical fingerprints could reorient cancer prevention, regulation, and litigation toward specific exposures rather than generic lifestyle factors.
