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.
NTP 11ROC: Ochratoxin A increased the incidence and multiplicity of fibroadenomas of the mammary gland in female rats.

Review
One of three studies reports mammary tumors: NTP TR 358. Two studies did not show mammary tumors: Bendele 1985 and Purchase 1971.

Review
When administered by gavage, ochratoxin A increased the incidence and multiplicity of fibroadenomas of the mammary gland in female rats (IARC 1993, NTP 1989).
