This just in: house mice cause breast cancer

And I’m not kidding. It seems that a mouse mamillary tumor virus can jump from mice to humans and is found in 40% – 60% of human breast tumour cases in continental populations where mice are prevalent. Furthermore, genetic fragments of the mouse virus are found in as many as 15% of the U.S. population, presumably putting those people at greater risk for breast cancer.

This ecological and evolutionary perspective gives us a chance to fight, detect, and even prevent breast cancer. Deep thanks to The Examining Room of Dr. Charles for this one.
