Abstract: This study introduces an innovative method for timely brain Tumor detection using a Convolutional Neural Network (CNN) architecture, specifically employing the VGG16 model for feature extraction and transfer learning. Given the critical importance of early diagnosis, traditional manual image interpretation methods are replaced by deep learning techniques, which have shown promise in automating medical image analysis tasks. By leveraging the hierarchical representations learned by VGG16 on extensive image datasets, the proposed approach enhances detection accuracy and robustness. Evaluation on a benchmark dataset of MRI scans demonstrates the superiority of the CNN model with VGG16 over traditional machine learning methods and other deep learning architectures. Performance metrics such as accuracy, sensitivity, specificity, and AUC-ROC validate the effectiveness of the proposed method. Overall, this research offers a reliable and efficient solution for automated brain Tumors diagnosis, potentially revolutionizing clinical decision-making and patient management. By seamlessly integrating advanced technology with medical imaging, it addresses the critical need for early intervention and improved patient outcomes

1.Introduction
Brain Tumors pose a significant threat to human health, with both benign and malignant forms affecting millions worldwide.Timelydetectioniscritical,andrecentadvancementsinmedicaltechnologyofferpromisingsolutionsthrough Artificial Intelligence (AI) and Machine Learning (ML)[1]. Utilizing sophisticated algorithms like Convolutional Neural Networks(CNNs)andtheVGG16model,AI-poweredsoftwarecanaccuratelydetectandclassify TumorsfromMRIscans. Traditional methods of Tumorsdetection relyon manual interpretation of MRIimages,a processthat islabour-intensive and subjective [2]. However, the emergence of deep learning techniques, particularly CNNs, has revolutionized medical image analysis, providing automated and precise Tumors identification. Transfer learning further enhances accuracy by adapting pre-trained models like VGG16 to the specifics of brain MRI data. Automated Tumors detection systems are essential given the severity of brain Tumors and the limitations of manual interpretation. Magnetic Resonance Imaging (MRI) remains the primary diagnostic tool due to its ability to provide detailed images without radiation exposure [3]. Earlydetectionsignificantly impactspatientsurvival rates,underscoringtheimportanceof advancedimaging techniques in medical practice. Brain Tumors encompass a diverse range of abnormalities, both benign and malignant, impacting variousaspectsofhumanhealth.Itiscrucial todetectthese Tumors early,astheycanleadtosevereconsequencesifleft untreated[4].Recentadvancementsinmedicaltechnology,particularlyintherealmofAIandML,offerpromisingavenues for early detection and classification of brain Tumors.

Traditional styles of brain excrescence discovery, similar as glamorous resonance imaging (MRI) and reckoned tomography (CT) reviews, calculate on homemade interpretation by radiologists, which can be timeconsumingand prone to mortal error [8]. Accordingly,there'sa growing need forautomated and intelligent systems that can help in the discovery and bracket of brain excrescences with high delicacy and effectiveness.

CNNs have the capability to automatically learn hierarchical representationsofdata,makingthemwell-suitedforimagebrackettasks[10].Severalstudieshaveexploredtheoperation ofCNNsforbrainexcrescencediscoveryandsegmentation,achievingpromisingresults[11].

In addition to CNNs, other machine literacy ways have been explored for brain excrescence discovery and bracket. These include support vector machines (SVMs) [15], probabilistic neural networks (PNNs) [8, 9], fuzzy clustering [13, 15], and ensemble styles [17, 18]. Still, deep literacy approaches have generally shown superior performanceduetotheircapabilitytolearncomplexrepresentationsfromrawdata[10].
Several studies have proposed mongrel or multi-modal approaches that combine different ways for brain excrescence discovery and segmentation. For case, some studies have combined traditional image processing ways, similar as thresholding, watershed algorithms, and fine morphology, with machine literacy or deep literacy models [20, 23]. Others have explored the use of multiple MRI modalities, similar as T1- ladened, T2- ladened, and fluid- downgraded inversion recovery (faculty) images, to ameliorate the performance of their models [22].
