Purpose: It is known that heat production in breast cancer is caused by
hypermetabolism, hypervascularization and hyperperfusion in the affected regions of the
breast. The object of this study is to detect the heat production in breast cancer of
Korean women.
Materials and Methods: 240 patients with breast cancer and benign mass were
examined by digital infrared thermographic system from January 1991 through December
1995. The heat production was detected when there was a hot spot on clinically palpable
breast mass area on the breast thermogram.
Results: Of the 240 patients, 130 with breast cancer and 110 with benign mass, as
control group. 118(90.8%) of 130 patients with breast cancer had the heat production, but
only 12(10.9%) of 110 patients with benign mass had the heat production(p<0.0001). The
sensitivity of breast thermogram was 90.8% and the specificity was 89.1%. 16(64%) of
25 breast cancer of which size was smaller than 2 cm had the heat production. But all
of 45 breast cancer of which size was larger than 4 cm had the heat production (p <
0.0001). 103(79.2%) of breast cancer had greater than 2¡É in thermal difference(¡âT), and
120(92.3%) had greater than 1¡É.
Conclusion: We conclude that there is heat production in breast cancer. And also the
heat production in breast cancer could be detected by the breast thermography. We
suggest that further studies of mechanism about heat production in breast cancer is
necessary.
