What is Computer-Aided Detection in Breast Cancer?
Computer-Aided Detection (CAD) in breast cancer uses deep learning algorithms to identify lesions in mammography, ultrasound, and MRI images, improving radiologist performance in screening programs.
CAD systems apply convolutional neural networks (CNNs) for lesion detection and false positive reduction, benchmarked against radiologists in clinical trials. Key works include Kooi et al. (2016) on large-scale deep learning for mammographic lesions (945 citations) and Yap et al. (2017) on automated ultrasound lesion detection (951 citations). Over 10 papers from 2016-2022 exceed 700 citations each, focusing on DL segmentation and classification.
Why It Matters
CAD boosts early breast cancer detection rates by 10-20% in screening, reducing mortality as shown in Kooi et al. (2016) trials comparing DL to radiologists. Yap et al. (2017) demonstrated ultrasound CAD matching expert performance, aiding resource-limited clinics. Yamashita et al. (2018, 4377 citations) overview CNN applications in radiology, enabling scalable deployment in national screening programs like those in Europe and Asia.
Key Research Challenges
False Positive Reduction
CAD systems generate high false positives in dense breasts, limiting clinical adoption. Kooi et al. (2016) report specificity challenges in mammograms despite high sensitivity. Balancing sensitivity-specificity remains key in DL models (Yamashita et al., 2018).
Dataset Variability
Limited annotated datasets hinder DL generalization across scanners and populations. Yap et al. (2017) highlight lack of standardized ultrasound data. Transfer learning reviews like Kim et al. (2022) address domain shifts in medical imaging.
Radiologist Integration
Ensuring CAD augments rather than replaces human judgment requires workflow studies. Tourassi et al. (2013) link gaze patterns to decisions, informing hybrid systems. Aggarwal et al. (2021) meta-analysis shows DL diagnostic accuracy but integration gaps persist.
