Weight of Evidence for Cancer (PDF) (17 pp, 135 K) Last Updated: 08/01/1991

WOE Characterization	Framework for WOE Characterization
C (Possible human carcinogen)	Guidelines for Carcinogen Risk Assessment (U.S. EPA, 1986)

Basis:

Based on an absence of human data and increased incidence of liver tumors in female mice. Except for a positive dominant lethal assay, there was no evidence of genotoxicity; this compound does, however, exhibit structural relationships to other nongenotoxic compounds classified as probable and possible human carcinogens.
This may be a synopsis of the full weight-of-evidence narrative.
