. . . .Thermography is completely non-contact and involves no form of energy imparted onto or into the body.

Thermography detects physiological changes in breast tissue and blood flow. Also known as digital infrared thermal imaging (DIII), thermography detects subtle changes by the use of ultra-sensitive infrared cameras to create an image of breast surface temperature. Advanced digital technology is used to detect, analyze and produce high resolution, diagnostic images of these temperature and vascular changes.

Thermography detection is based on the idea that cancer produces "hot spots" on the surface of skin over a known tumor. Research has shown that malignant change brings increased circulation and heat output. Most breast cancers are hotter than their arterial supply and venous drainage. . . .
