The aim of our study was to find out whether thermography (TG) could be used as a predictive method for early diagnosis of breast
cancer (BC). BC was induced with 2 doses of N-methyl-N-nitrosourea (50 mg/kg body weight) to 20 female Sprague Dawley
rats. Animals were maintained in temperature-controlled room (22°C) for 15 minutes and then imaged using digital infrared camera
(FLIR E40, FLIR Systems OÜ, Estonia). Anesthetized rats (isoflurane, 2ml/L of induction chamber volume) were positioned in front
of uniform pad and thermographic images were obtained in 0.5 meter from rats. Images were analyzed by software program (FLIR
Tools version 2.0, FLIR Systems, Inc., Wilsonville, USA). Symmetrical body areas were monitored to detect temperature patterns of
intact breast in compare to potential affected one. Only tumors developing non-parallel were further evaluated. The predictive role of
TG has been monitored and evaluated two weeks before tumor appearance. Rats developed 30 evaluable breast tumors – ductal forms
(20), papillary forms (9), and hyperplasia (1). Hyperplasia was accompanied by the raising temperature up to 0.2°C two weeks before
the palpation. Interestingly, almost all papillary forms of breast tumors (8/9) were characterized by elevated temperature up to 1.1°C.
Nonetheless, 11 ductal carcinomas (55%) were characterized by the increased temperature of 0.6±0.3°C. In 7 cases, temperature
sank by 0.5±0.3°C. Two tumors showed no differences in body temperature before manifestation. TG could be used as an effective
noninvasive predictive tool in BC diagnosis. However, more studies are required to describe the potential of this predictive method.
