Yes, it's done here in the US. There's a place here in Charlotte that offers breast thermography. It's more expensive than mammography and isn't covered by insurance.
Here's what is said about the difference. I have no personal experience with it. Just passing this along. The Difference Between Mammography and Thermal ImagingOn top of the radiation, compression, cost, and psychological issues caused by mammography, there is another thing that differentiates it from thermal imaging. The difference is in what the two detection systems look for: “Mammography and ultrasound depend primarily on structural distinction and anatomical variation of the tumor from the surrounding breast tissue…Infrared imaging detects minute temperature variations related to vascular flow and can demonstrate abnormal vascular patterns associated with the initiation and progression of tumors.”xxi In other words, thermal imaging can detect tumorous activity as it begins to develop a blood supply to sustain its growth. Any increased heat from a localized blood supply would suggest pathology. Yet for mammography, the tumor has to have formed sufficient physical mass and size to be detected.
