ILLUMINATING CANCER DETECTION: SPECTROSCOPY'S VITAL ROLE IN SCREENING AND DIAGNOSIS
Abstract
This paper explores the pivotal role of spectroscopy in cancer screening and diagnosis, shedding light on its significance in early detection and accurate characterization of cancerous tissues. Spectroscopic techniques offer unique capabilities for non-invasive and real-time analysis of tissue composition, providing valuable insights into biochemical and structural alterations associated with cancer development. By leveraging the inherent molecular signatures of tissues, spectroscopy enables clinicians to identify abnormal changes indicative of cancer presence, facilitating timely intervention and improved patient outcomes. This review examines the principles, methodologies, and applications of spectroscopy in cancer detection across various modalities, including Raman spectroscopy, fluorescence spectroscopy, and infrared spectroscopy. Additionally, it discusses recent advancements, challenges, and future directions in harnessing spectroscopic technologies for enhanced cancer screening and diagnosis.
