A Review on Non-Invasive Biosensors for Early Detection of Lung Cancer

According to the report of WHO, 2014, Lung Cancer has the highest death rate among men and women around the world. However, there is a lack of awareness about the early diagnosis and screening methods for Lung Cancer. Early diagnosis helps to reduce the rate of mortality, hence finding new ways to decrease the deaths due to Lung Cancer become the need of the hour. The existing clinical screening techniques used for detection are mostly imaging techniques or invasive methods. These methods either have low sensitivity or highly expensive for most people. The Present work aims to develop Non-Invasive sensors based on Optical, Electrochemical and Piezoelectric techniques. This Paper reviews the recent Non-Invasive biosensor-based screening techniques for Lung Cancer detection at early stages. Advanced development of Non-Invasive biosensors offers advantages of Portability, comfort, ease of use and low cost. This review paper outlines conventional techniques used for the detection process along with some newly developed Biosensors.
