Induction of mammary tumors with metronidazole in female Sprague-Dawley rats

Tumori. 1984 Aug 31;70(4):307-11.


Sprague-Dawley rats were administered low doses of metronidazole similar to those used in humans, and then subjected to a long-term follow-up. Metronidazole caused a significant rise in mammary tumors in the female rats (p less than 0.001) after a mean latency period of 100.5 weeks.
