The global oral cancer diagnosis market is experiencing robust growth, driven by rising prevalence of oral cancers, advancements in diagnostic technologies, and increasing awareness about early detection. The market, estimated at $2.5 billion in 2025, is projected to expand at a Compound Annual Growth Rate (CAGR) of 7% from 2025 to 2033, reaching approximately $4.2 billion by 2033. This growth is fueled by the adoption of sophisticated diagnostic techniques like visual inspection with toluidine blue, brush cytology, and advanced imaging modalities such as cone beam computed tomography (CBCT) and optical coherence tomography (OCT). The increasing geriatric population, coupled with lifestyle factors like tobacco and alcohol consumption, contributes significantly to the higher incidence of oral cancer, thereby boosting market demand. Furthermore, the development of minimally invasive diagnostic tools and point-of-care testing is streamlining the diagnostic process and improving patient outcomes, furthering market expansion. Key players in the market, including GE Healthcare, Roche, Thermo Fisher Scientific, Siemens Healthineers, and others, are continuously investing in research and development to improve diagnostic accuracy and efficacy. The market is segmented based on technology (visual inspection, cytology, biopsy, imaging), end-user (hospitals & clinics, research labs), and geography. While North America and Europe currently dominate the market due to established healthcare infrastructure and high awareness, developing regions in Asia-Pacific and Latin America are witnessing significant growth potential owing to rising disposable incomes and improved healthcare accessibility. However, high costs associated with advanced diagnostic technologies and a lack of awareness in certain regions pose challenges to market expansion. The future of the oral cancer diagnosis market is promising, with ongoing innovation focusing on early detection, personalized medicine, and improved patient accessibility.

Early detection of oral cancer necessitates a minimally invasive, tissue-specific diagnostic tool that facilitates screening/surveillance. Brush biopsy, though minimally invasive, demands skilled cyto-pathologist expertise. In this study, we explored the clinical utility/efficacy of a tele-cytology system in combination with Artificial Neural Network (ANN) based risk-stratification model for early detection of oral potentially malignant (OPML)/malignant lesion. A portable, automated tablet-based tele-cytology platform capable of digitization of cytology slides was evaluated for its efficacy in the detection of OPML/malignant lesions (n = 82) in comparison with conventional cytology and histology. Then, an image pre-processing algorithm was established to segregate cells, ANN was trained with images (n = 11,981) and a risk-stratification model developed. The specificity, sensitivity and accuracy of platform/ stratification model were computed, and agreement was examined using Kappa statistics. The tele-cytology platform, Cellscope, showed an overall accuracy of 84–86% with no difference between tele-cytology and conventional cytology in detection of oral lesions (kappa, 0.67–0.72). However, OPML could be detected with low sensitivity (18%) in accordance with the limitations of conventional cytology. The integration of image processing and development of an ANN-based risk stratification model improved the detection sensitivity of malignant lesions (93%) and high grade OPML (73%), thereby increasing the overall accuracy by 30%. Tele-cytology integrated with the risk stratification model, a novel strategy established in this study, can be an invaluable Point-of-Care (PoC) tool for early detection/screening in oral cancer. This study hence establishes the applicability of tele-cytology for accurate, remote diagnosis and use of automated ANN-based analysis in improving its efficacy.
