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.
One study reported increased malignant mammary tumors in female rats.
Citations to review sources and individual studies reporting mammary gland tumors are listed below.
