Cancer is one of the most deadly diseases, and current detection options are ineffective. Recently, a large amount of research has been conducted for the development of biosensors able to detect cancer biomarkers. Many biosensors have been created for cancer detecting purposes. I examined literature reviews outlining current biosensing methods. These reviews provided an overview of the sensing techniques that are currently in existence as well as evaluations of their effectiveness. I also read experimental reports that outline the construction of biosensors fabricated in laboratories and the results of their testings. These papers help to showcase the feasibility and effectiveness that a biosensor has when detecting cancer. In this paper I discuss signal transduction systems, piezoelectric sensors, carbon nanotubes, quantum dots, and raman signals for use as cancer biosensors. Since cancer is such a deadly disease, an accurate biosensor is needed that can detect cancer earlier than current methods. In this paper I will provide an overview of each method along with an evaluation to determine what cancer detecting system is the best.
