Background Information on the RoC: The RoC is a congressionally mandated, science-based, public health report that identifies agents, substances, mixtures, or exposures (collectively called “substances”) in our environment that pose a cancer hazard for people in the United States. The NTP prepares the RoC on behalf of the Secretary of Health and Human Services. The NTP follows an established, four-part process for preparation of the RoC (http://ntp.niehs.nih.gov/go/rocprocess). Published biennially, each edition of the RoC 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 (available at http://ntp.niehs.nih.gov/go/roc12). The 13th RoC is under development.
