Lung cancer rem.ins a m.jor concern in m.dern oncology due to its high m.rtality rates and m.ltifaceted origins, including hereditary factors and various clinical changes. It stands as the deadliest type of cancer and a significant cause of cancer-related deaths globally. Early diagnosis enables healthcare providers to adm.nister appropriate treatm.nt m.asures prom.tly and accurately, leading to im.roved prognosis and higher survival rates. The significant increase in both the incidence and m.rtality rates of lung cancer, particularly its ranking as the second m.st prevalent cancer am.ng wom.n worldwide, underscores the need for com.rehensive research into efficient screening m.thods. Advances in diagnostic techniques, particularly the use of com.uted tom.graphy (CT) scans, have revolutionized the identification of lung cancer. CT scans are renowned for their ability to provide high-resolution im.ges and are particularly effective in detecting sm.ll, calcified areas, crucial for identifying early-stage lung cancer. Consequently, there is growing interest in enhancing com.uter-aided detection (CAD) system.. These algorithm. assist radiologists by reducing false-positive interpretations and im.roving the accuracy of early cancer diagnosis. This study aim. to enhance the effectiveness of CAD system. through various m.thods. Initially, the Contrast Lim.ted Adaptive Histogram.Equalization (CLAHE) algorithm.is em.loyed to preprocess CT scan im.ges, thereby im.roving their visual quality. Further refinem.nt is achieved by integrating different optim.zation strategies with the CLAHE m.thod. The Cutm.x data augm.ntation technique is applied to boost the perform.nce of the proposed m.del. A com.arative analysis is conducted using deep learning architectures such as Inception-V3, Resnet101, Xception, and Efficientnet. The study evaluates the perform.nce of these architectures in im.ge classification tasks, both with and without the im.lem.ntation of the CLAHE algorithm. The em
