Cancer Assessment

Weight of Evidence for Cancer (PDF) (14 pp, 119 K) Last Updated: 12/01/1990

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:
  • Based on inadequate human data and sufficient evidence of carcinogenicity in animals; namely, significantly increased incidences of benign and malignant tumors at multiple sites in one strain of female mice treated orally, dermally, and by inhalation. There is also evidence of mutagenicity in a variety of test systems.
  • This may be a synopsis of the full weight-of-evidence narrative.
