The Report on Carcinogens is a congressionally mandated listing of substances that either are known to be human carcinogens or may reasonably be anticipated to be human carcinogens, and to which a significant number of persons residing in the United States are exposed [Section 301(b)(4) of the Public Health Service Act, 42 U.S.C. 241(b)(4)].
The Report 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 Report evaluation.
The Office of Report on Carcinogens conducts cancer hazard evaluations on the nominated substances.
Draft Report monographs are released for public comment and peer review before finalization.
NTP submits the proposed listing of newly reviewed substances to the U.S. Department of Health and Human Services secretary for review, approval, and release to the public and congressional members.
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.
The Report is prepared by the Office of the Report on Carcinogens, under the direction of Ruth Lunn, Dr.P.H. Contract support for preparation of the Report in FY 2016 was provided by Integrated Laboratory Systems Inc. and ICF.
