ILLUMINATING CANCER DETECTION: SPECTROSCOPY'S VITAL ROLE IN SCREENING AND DIAGNOSIS

Аннотация

INTRODUCTION composition of tissues, providing clinicians with a Cancer remains one of the most pressing global powerful tool for cancer detection and health challenges, with early detection playing a characterization. By analyzing the unique spectral crucial role in improving patient outcomes. signatures of tissues, spectroscopy enables the Traditional cancer screening and diagnostic identification of subtle alterations indicative of methods often rely on invasive procedures and cancer presence, allowing for early intervention time-consuming histopathological analysis, which and personalized treatment strategies. Moreover, may delay diagnosis and limit treatment options. In spectroscopy offers the advantage of rapid, label- recent years, spectroscopy has emerged as a free, and in situ analysis, making it well-suited for promising technology for non-invasive and real- screening large populations and monitoring time assessment of tissue composition, offering disease progression over time. valuable insights into the biochemical and structural changes associated with cancer This paper aims to provide a comprehensive development. overview of the vital role of spectroscopy in illuminating cancer detection and diagnosis.
