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 1999: When administered orally, produced an increased incidence of mammary gland tumors in rats. An NTP study of 1,4-dioxane did not find mammary gland tumors.
Citations to review sources and individual studies reporting mammary gland tumors are listed below.
