What is the difference between thermography and mammography?

0

Thermography uses no radiation or compression of delicate breast tissue during the scan making it completely safe and painless. Thermography is a test of physiology or function and can detect the earliest signs of angiogenesis or blood vessel growth. Because blood vessels ordinarily start to grow before any other significant changes a thermogram can see these abnormal physiological processes as early as five to ten years before a cancer can be seen by a mammogram, MRI, or ultrasound or felt by a physical exam. Age or breast density is not a factor with thermography. Mammography uses radiation and compression of breast tissue in a test of anatomy or structure. Mammography looks for evidence of a growth or tumor within the breast tissue. By the time a mammogram can detect evidence of a tumor, it may have been growing for several years. Suspicious areas must be dense enough to be seen. In Canada mammography is contraindicated for women under 50.

Thermography uses no radiation or compression to achieve its images. Thermography is a test of physiology (activity), while Mammography is a test of structure.
