The major difficulty in the interpretation of breast thermography is the complexities of the vascular patterns (false negatives and false positives), and a secondary problem is the existence of cold tumors (false negatives). To overcome these difficulties, we investigated dynamic thermography after cold stress. When a breast is exposed to cold stress, the vascular pattern disappears, and after the stress is removed, the pattern gradually recovers. This phenomenon of thermal recovery can be visualized by sequential thermography or by digital subtraction thermography. In this study, we have attempted to increase the sensitivity of breast thermography by using thermal recovery and sequential and subtraction thermography, hoping that even small tumors with negative steady-state thermography may appear in dynamic thermography
