About the Report on Carcinogens
Report on Carcinogens
The Report on Carcinogens (RoC) is a congressionally mandated, science-based, public health report that identifies agents, substances, mixtures, or exposures (collectively called "substances") in our environment that may potentially put people in the United States at increased risk for cancer.
The National Toxicology Program (NTP) prepares the RoC on behalf of the Secretary, Health and Human Services.
Published biennially, each edition of the report is cumulative and consists of substances newly reviewed in addition to those listed in previous editions. . The 12th RoC, the latest edition, was published on June 10, 2011. The 13th RoC is under development.
For each listed substance, the RoC contains a substance profile, which provides information on:
- cancer studies that support the listing—including those in humans, animals and on possible mechanisms of action
- potential sources of exposure to humans
- current Federal regulations to limit exposures
