Raman spectroscopy has emerged as a valuable analytical instrument for liver cancer detection, providing rapid, label-free, and non-destructive molecular profiling of biological specimens. Raman-based methodologies can discern malignant from nonmalignant conditions by analyzing small biochemical alterations in biofluids, including blood, urine, and exosomes, as well as in liver tissue, yielding unique spectrum fingerprints. Progress in chemometric analysis, including machine learning models and multivariate statistical methods, has significantly improved the diagnostic precision of Raman spectroscopy, attaining elevated sensitivity and specificity across numerous studies. Furthermore, the integration of complementary techniques, such as surface-enhanced Raman spectroscopy (SERS) and Raman optical activity (ROA) has broadened its prospects for clinical application. This review article elucidates the contemporary applications of Raman spectroscopy in the diagnosis of liver cancer, presents pivotal findings across various sample types, and examines the challenges and future prospects of building Raman-based platforms as dependable diagnostic instruments in oncology.  \nAcademic Editor: Giovanni Tarantino  \nReceived: 28 January 2026  \nRevised: 13 February 2026  \nAccepted: 18 February 2026  \nPublished: 20 February 2026  \nCopyright: © 2026 by the authors.

Introduction  \nLiver cancer rates rank sixth among all cancers globally, and is the third major cause of cancer-related mortality [1] . Early-stage liver cancer treatment can ensure a favorable prognosis and comparatively greater survival rate. Late diagnosis, on the other hand, leads to a poor prognosis where the survival rate is relatively low. Absence of nerves in the liver leads to mainly asymptomatic cancer during the early stages [2] . Currently, there are two prevalent screening methods for liver cancer: imaging and serological biomarker assessments [3] . Current imaging modalities comprise ultrasound imaging, magnetic resonance imaging, and computed tomography (Figure 1) [3] .  \nFigure 1. Current Imaging-Based Methods for Liver Cancer Diagnosis (Created in [https://BioRender.com](https://BioRender.com)).  \nHowever, these methods possess numerous drawbacks. Sensitivity of ultrasound imaging is highly variable, contingent upon the operator’s expertise and precision of the equipment.
