                                                  1.Introduction

             Diagnosing brain tumors using magnetic resonance imaging (MRI) is a complex task due to variations in tumor size, shape, and spatial distribution [1] [2]. Traditional
             classification models often face challenges such as imbalanced datasets, low precision, and limited interpretability, which can result in biased learning and reduced accuracy [3].
             This work addresses these challenges by integrating image processing, transfer learning (TL), and Generative Adversarial Networks (GANs) to enhance MRI-based tumor
             classification. EfficientNetB0 is used for feature extraction, while DCGANs generate synthetic data to mitigate class imbalance and improve model robustness. Additionally,
             explainable AI techniques such as LIME enhance transparency [4] in model predictions. The primary goal of this study is to explore a comparative analysis between GANs and
             diffusion models to determine the most effective approach for early and reliable brain tumor classification.
