Breastlight is a new product to improve breast health awareness of women. However, its accuracy in detection of breast lesions (BLs) is unknown. The aim of this study was to determine the Breastlight accuracy in detection of BLs.
From July 2011 to September 2013, a total of 500 women referred to mammography unit in Yazd, Iran for screening were recruited to the study. The sensitivity and specificity of Breast light was measured with clinical breast examination (CBE), mammography and sonography. Sonographic and mammography examinations were performed according to breast density among women in two groups of younger (n = 105) and older (n = 395) than 30 years.
The results have shown a statistically significant positive correlation between Breastlight, CBE, sonography, and mammography in detection of BLs. Breastlight significantly detected 60.3%, 35.8%, and 59% of lesions which were detected by mammography, CBE, and sonography, respectively. Its sensitivity varied significantly with breast density. Comparing the sensitivity of Breastlight among women younger and older than 30 years indicated that the Breastlight had a higher sensitivity for women older than 30 years. The greatest and lowest portion of positive predictive value occurred with CBE (94.7%) and mammography (91.1%). As well, its greatest and lowest portion of negative predictive value occurred with CBE (65.6%) and sonography (29.7%).
The results of this study showed that the efficacy of Breastlight in detection of breast changes as domestic apparatus was appropriate. However, it is recommended further studies to evaluate the Breastlight efficacy and accuracy in detection of the BLs.
Breastlight是一款旨在提高女性乳房健康意识的新产品。然而，其在检测乳腺病变（BLs）方面的准确性尚不清楚。本研究的目的是确定Breastlight在检测BLs方面的准确性。
2011年7月至2013年9月，共有500名转诊至伊朗亚兹德乳腺摄影科进行筛查的女性被纳入本研究。通过临床乳腺检查（CBE）、乳腺摄影和超声检查来测量Breastlight的敏感性和特异性。根据年龄将女性分为两组，年龄小于30岁的105名和年龄大于30岁的395名，针对这两组女性，依据乳房密度进行超声和乳腺摄影检查。
结果显示，在检测BLs方面，Breastlight、CBE、超声和乳腺摄影之间存在统计学上显著正相关。Breastlight分别显著检测出乳腺摄影、CBE和超声所检测到的病变的60.3%、35.8%和59%。其敏感性随乳房密度有显著差异。比较30岁以下和30岁以上女性中Breastlight的敏感性表明，Breastlight对30岁以上女性具有更高的敏感性。阳性预测值的最高和最低比例分别出现在CBE（94.7%）和乳腺摄影（91.1%）中。同样，阴性预测值的最高和最低比例分别出现在CBE（65.6%）和超声（29.7%）中。
本研究结果表明，Breastlight作为一种家用设备在检测乳房变化方面的效果是合适的。然而，建议进一步开展研究以评估Breastlight在检测BLs方面的效果和准确性。
