The current lifestyle contributes to the increase in the incidence of life-threatening illness like cancer. Methods for early detection of the same can help better patient outcomes. Effective, inexpensive and non-invasive diagnostic methods are often sensitive as well as specific compared to conventional mechanisms. Advances in biosensor technologies have paved the way for low-cost, non-invasive diagnostic techniques that report greater levels of sensitivity and specificity. Organic Light-Emitting Diodes (OLEDs) have emerged as a proficient biosensor for clinical diagnostics. This research rigorously investigates the application of OLED-based biosensors for early-stage cancer detection. In addition, a comprehensive analysis of OLED characteristics pertinent to the detection of various cancer types, such as cutaneous and ovarian malignancies, is also reported. We also explore the integration of OLEDs into portable and adaptable diagnostic devices, with the aim of improving their screening capabilities. A parameterized evaluation framework is used to assess the design attributes and operational efficacy of OLED biosensors, emphasizing their suitability for oncological diagnostic applications.
