It typically originates in the lung tissues, particularly in the cells lining the airways, and early detection is crucial for improving patient survival rates. Computed tomography (CT) imaging has become a standard tool for lung cancer screening, providing detailed insights into lung structures and facilitating the early identification of cancerous nodules. In this study, an improved Faster R-CNN model is employed to detect early-stage lung cancer. To enhance the performance of Faster R-CNN, a novel dual-attention optimized multi-scale CNN (DA OMS-CNN) architecture is used to extract representative features of nodules at different sizes. Additionally, dual-attention RoIPooling (DA-RoIpooling) is applied in the classification stage to increase the model\u2019s sensitivity. In the false-positive reduction stage, a combination of multiple 3D shift window transformers (3D SwinT) is designed to reduce false-positive nodules. The proposed model was evaluated on the LUNA16 and PN9 datasets. The results demonstrate that integrating DA OMS-CNN, DA-RoIPooling, and 3D SwinT into the improved Faster R-CNN framework achieves a sensitivity of 96.93% and a CPM score of 0.911. Comprehensive experiments demonstrate that the proposed approach not only increases the sensitivity of lung cancer detection but also significantly reduces the number of false-positive nodules. Therefore, the proposed method can serve as a valuable reference for clinical applications.<\/jats:p>","DOI":"10.3390\/informatics12030065","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T08:58:23Z","timestamp":1751878703000},"page":"65","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["DA OMS-CNN: Dual-Attention OMS-CNN with 3D Swin Transformer for Early-Stage Lung Cancer Detection"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-2809-260X","authenticated-orcid":false,"given":"Yadollah","family":"Zamanidoost","sequence":"first","affiliation":[{"name":"Department of Computer Engineering, Polytechnique Montr\u00e9al, Montreal, QC H3T 1J4, Canada"}]},{"given":"Matis","family":"Rivron","sequence":"additional","affiliation":[{"name":"National Institute of Sciences, INSA Lyon, 69621 Villeurbanne, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9000-5467","authenticated-orcid":false,"given":"Tarek","family":"Ould-Bachir","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Polytechnique Montr\u00e9al, Montreal, QC H3T 1J4, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4234-9959","authenticated-orcid":false,"given":"Sylvain","family":"Martel","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Polytechnique Montr\u00e9al, Montreal, QC H3T 1J4, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Balyan, A.K., Ahuja, S., Lilhore, U.K., Sharma, S.K., Manoharan, P., Algarni, A.D., Elmannai, H., and Raahemifar, K.
