Abstract:
Background: Breast cancer is the second cause of death from cancer among Mexican women but the incidence continues to rise mainly in rural communities. However, among women older than 50 years, only 7% of them report having had a mammogram because of insufficient number of mammography equipment and trained health care professionals. Mammography has limitation in sensitivity and specificity greater than 70 % and greater than 80 %, respectively. Breast thermography is a noncontact, noninvasive technique and easy to use outside hospitals. We propose to evaluate the feasibility of thermal infrared imaging as screening tool for early detection of breast cancer. Methods: Between November 2006 and December 2008, women were offered clinical breast examination (CBE) followed by breast thermography and mammography, and biopsy if indicated. Thermal infrared imaging was obtained by using an infrared camera (DL-700; 320*240 UFPA, Zhejiang Dali Technology Co., Ltd.). Infrared imaging was performed in a controlled environment with temperature and humidity maintained between 18 ºC and 23 ºC. Breast thermography diagnosis was established according to Hobbins criteria where TH1 to TH5 are equivalent to BI-RADS I to V (Intermer J of Rad 1987;12:337). CBE and breast thermography were correlated with mammography and histologic diagnosis. Results: Nine hundred and eleven (100%) women (median age 44 years, range 15-83) were evaluated. Five hundred and three (55%) of them were older than 40 years, 137 (15%) were between 35 and 39 years. Cancer was diagnosed in 14 (3%) and 2 (1.4%) women, respectively. Overall cancer was diagnosed in 16 (2.5 %) out of 640 women older 35 years. Among 116 (13%) women between 30 and 34 years, cancer was found in 1 (0.8 %) patient. Cancer was not found among 155 (17%) women between 15 and 29 years. Conclusions: In this study cancer was diagnosed in 1.8 % of women by using breast thermography. Thermal infrared imaging allows to select patients who could require further work-up. Breast thermography emerges as a potential screening tool for early detection of breast cancer.
