Special Issue Information

Dear Colleagues,

Breast cancer is a complex and heterogeneous disease that affects millions of women worldwide. In recent years, significant advancements have been made in the fields of precision medicine, diagnostics, and novel treatment options for patients with breast cancer. Precision medicine allows for more personalized and targeted treatment strategies based on an individual's unique genetic makeup, helping to improve patient outcomes and reduce the risk of recurrence. Diagnostic tools, such as genetic testing and imaging techniques, have also evolved to provide more accurate and early detection of breast cancer, leading to better prognosis and survival rates.

Novel treatment options, such as immunotherapy and targeted therapies, are revolutionizing the way breast cancer is treated, offering more effective and less toxic alternatives to traditional chemotherapy. These innovative approaches are paving the way for more personalized and tailored treatment plans for patients with breast cancer, ultimately improving survival rates and patients’ quality of life. In this era of rapid advancements in breast cancer research, it is crucial to continue exploring new avenues in precision medicine, diagnostics, and treatment options to further improve outcomes for patients battling this devastating disease.

The early and accurate detection of breast lesions through mammography is crucial for improving survival rates. However, the existing deep learning-based methods often rely on costly pixel-level annotations, limiting their scalability in real-world applications. To address this issue, a novel local extremum mapping (LEM) mechanism is proposed for mammogram classification and weakly supervised lesion localization. The proposed method first divides the input mammogram into multiple regions and generates score maps through convolutional neural networks. Then, it identifies the most informative regions by filtering local extrema in the score maps and aggregating their scores for final classification. This strategy enables lesion localization with only image-level labels, significantly reducing annotation costs. Experiments on two public mammography datasets, CBIS-DDSM and INbreast, demonstrate that the proposed method achieves competitive performance. On the INbreast dataset, LEM improves classification accuracy to 96.3% with an AUC of 0.976. Furthermore, the proposed method effectively localizes lesions with a dice similarity coefficient of 0.37, outperforming Grad-CAM and other baseline approaches. These results highlight the practical significance and potential clinical applications of our approach, making automated mammogram analysis more accessible and efficient. Full article

Breast cancer is the most commonly diagnosed cancer worldwide, underscoring the critical need for effective early detection methods to reduce mortality. Traditional detection techniques, such as mammography, present significant limitations, particularly in women with dense breast tissue, highlighting the need for alternative screening approaches. Breathomics, based on the analysis of Volatile Organic Compounds (VOCs) present in exhaled breath, offers a non-invasive, potentially transformative diagnostic tool. These VOCs are metabolic byproducts from various organs of the human body whose presence and varying concentrations in breath are reflective of different health conditions. This review explores the potential of breathomics, highlighting its promise as a rapid, cost-effective screening approach for breast cancer, facilitated through the integration of portable solutions like electronic noses (e-noses). Key considerations for clinical translation—including patient selection, environmental confounders, and different breath collection methods—will be examined in terms of how each of them affects the breath profile. However, there are also challenges such as patient variability in VOC signatures, and the need for standardization in breath sampling protocols. Future research should prioritize standardizing sampling and analytical procedures and validating their clinical utility through large-scale clinical trials. Full article
