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 U.S. are exposed [Section 301(b)(4) of the Public Health Service Act, 42 U.S.C. 241(b)(4)].
The RoC is a cumulative report and consists of substances newly reviewed, in addition to those listed in previous editions. NTP follows an established four-part process for preparing the report.
Each substance listed in the RoC has a profile, which contains the listing status determined by using established listing criteria, and a summary of the cancer studies supporting the listing status, information on human exposure, and federal regulations to reduce exposure.
Preparation of the RoC is conducted by the Office of the Report on Carcinogens, under the direction of Ruth Lunn, Dr.P.H. Contract support for preparation of the RoC in FY 2016 was provided by Integrated Laboratory Systems Inc. and ICF.
