Abstract :

Early detection of cancer significantly improves the chances of successful treatment and patient survival. Medical imaging technologies play a pivotal role in identifying malignancies at their initial stages. This review explores various imaging modalities such as X-ray, CT, MRI, PET, ultrasound, and mammography, evaluating their effectiveness, advantages, and limitations in early cancer diagnosis. Each method offers unique benefits in terms of sensitivity, resolution, accessibility, and application to specific cancer types. Furthermore, recent advancements such as AI-assisted image analysis and hybrid imaging techniques are also discussed, highlighting their contribution to more accurate and early diagnoses. The article emphasizes the importance of integrating advanced imaging with clinical and molecular data to optimize early cancer detection strategies.
