The Report on Carcinogens (RoC) is a congressionally mandated listing of substances that either are known to be human carcinogens or might reasonably be anticipated to be human carcinogens, and to which a significant number of people residing in the United States are exposed [Public Health Service Act, 42 U.S.C. 241(b)(4)]. Preparation of the RoC at NTP is under the direction of Ruth Lunn, Dr.P.H., director of the NIEHS/NTP Office of Report on Carcinogens (ORoC).
The RoC is cumulative, consisting of newly reviewed substances in addition to those substances listed in previous editions. NTP follows an established four-part process when preparing the report.
NTP selects nominations for evaluation.
ORoC conducts cancer hazard evaluations on the selected substances and prepares draft RoC monographs.
Draft RoC monographs are released for public comment and external peer review is conducted before finalization.
NTP submits the proposed listing of newly reviewed substances to the Secretary of Health and Human Services for review and approval, followed by transmittal to Congressional and publication on the NTP website.
Each substance listed in the report has a profile, which contains the listing status determined by using established listing criteria, a summary of the cancer studies supporting the listing status, information on human exposure, and federal regulations to reduce exposure.Additional Links for the Report on Carcinogens:
