Role of Sensor Technology in Detection of the Breast Cancer

Cancer has proven to be a menace for researchers from the past few decades. Breast cancer is a form of cancer with the second-highest mortality rate in the world. It is the leading form of cancer among women worldwide. Lack of early detection mechanism and detection at terminal stages result in this high mortality rate. Present detection mechanisms, including mammography, x-rays, positron emission tomography, or biopsy, prove to be ineffective in detecting breast cancer at early stages. Sensor technology has given new hope for solving this problem. With the advent of nanotechnology, sensors have become more sensitive, specific, and cost-effective. The sensor innovation has offered to ascend to an excess of sensors that can be utilized for early discovery of breast cancer with high explicitness with backsliding cases in individual breast cancer patients. This review puts light on different sensors developed to detect breast cancer over the past few years. Graphical abstract
