I don't think I mentioned it anywhere in the Rent-a-Flir thread, but Wikipedia has an

Including history, technology, and uses for Thermal Imaging, including this image which illustrates how Thermal Imaging is used for breast cancer screening, and eliminates the need for exposing women to X-ray, which may contribute to breast cancer.
