Weight of Evidence for Cancer (PDF) (10 pp, 100 K) Last Updated: 09/07/1988

WOE Characterization Framework for WOE Characterization
B2 (Probable human carcinogen - based on sufficient evidence of carcinogenicity in animals) Guidelines for Carcinogen Risk Assessment (U.S. EPA, 1986)
Basis:
  • Classification is based on induction of local carcinomas following inhalation and subcutaneous exposures in rats, tumor induction in rats following prenatal exposure, and evidence suggestive of carcinogenicity in hamsters and mice by inhalation. Dimethyl sulfate alkylates cellular macromolecules and is genotoxic.
  • This may be a synopsis of the full weight-of-evidence narrative.
