“…Ghartey et al [28] screened 2204 women in Ghana and reported a sensitivity of 92.3% with the device as compared to 73% with CBE; however, specificity remains unreported (Figure5a-c). We agree with other authors [37,38] that there is a need for more clinical trials before using the transillumination method as a rapid diagnostic tool as it does offer a potentially accurate tool that is inexpensive and very easy to use. The varying sensitivity showcases the need for the rapid diagnostic tool which can delineate between normal and abnormal breast based on biomarkers such as hemoglobin, lipids, collagen, water and tissue properties such as absorption coefficient, reduced scattering coefficient, oxygen saturation, and tissue oxygenation index.…”

“…Transillumination imaging has been studied using a commercial tool such as Breastlight [29,30] and has been found to have varying sensitivities between 60% and 93% for breast cancer detection, primarily due to the dependency on the skill of the clinician to visually analyze the transillumination images. [28,[30][31][32][33][34][35][36] Mehnati et al [37] and Edge et al [38] critically review the transillumination imaging for breast screening and recommended performing more clinical trials.…”

There have been substantial advancements in optical spectroscopybased imaging techniques in recent years. These developments can potentially herald a transformational change in the diagnostic pathway for diseases such as cancer. In this paper, we review the clinical and engineering aspects of novel optical spectroscopy-based imaging tools. We provide a comprehensive analysis of optical and non-optical spectroscopy-based breast cancer diagnosis techniques vis-a-vis the current standard techniques such as X-Ray mammography, ultrasonography, and tissue biopsy. The recent advancements in optical spectroscopy-based imaging systems such as Transillumination Imaging (TI) and the various types of Diffuse Optical Imaging (DOI) systems (parallel-plate, bed-based, and handheld) are examined. The engineering aspects, including mechanical, electronics, optics, automatic interpretation using artificial intelligence (AI), and ergonomics are discussed. The abilities of these technologies for measuring several cancer biomarkers such as hemoglobin, water, lipid, collagen, oxygen saturation (SO2), and tissue oxygenation index (TOI) are investigated. This article critically assesses the diagnostic ability and practical deployment of these new technologies to differentiate between the normal and cancerous tissue.
