Thermography is thermal infrared images that are used to detect lesions in breasts. These Thermographic detect the heat pattern and blood flow of the different regions of the breast. Regions with warmer temperatures are more likely to contain tumors than normal tissue. The infrared thermal imaging method can analyze breast cancer using dynamic Thermograms and also it can selectively optimize the contrast in areas of dense tissues in young women.

When tumors develop, cancer cells grow. These cells need additional blood to reproduce. So the blood flow increases for this purpose, and the skin in that area will become warmer. By using digital infrared imaging, thermography can detect subtle changes in the breast by revealing areas of heat and cold.
