Mammary gland tumor summary
A summary of findings related to mammary gland tumors, most often excerpted from IARC Monographs or the NTP 11th ROC, and, in some cases, supplemented by our evaluation of individual studies and reviews, is available for the priority chemicals and 67 others.
IARC 1983: When administered in the diet, produced benign and malignant mammary tumors in rats of both sexes.

Review
Female rats fed a diet containing AF-2 developed mammary tumors: Cohen 1977. Male and female rats fed a diet containing AF-2 developed benign and malignant mammary tumors: Takayama 1977a, Takayama 1977b.

Review
Two of six studies report mammary tumors: Takayama 1977 and Cohen 1977. Four studies did not report mammary tumors: Kinebuchi 1979, Sano 1977, Yokoro 1977 and Miyaji 1971.
