A method that is specific and reliable for detecting cancers at early stages and of at an affordable cost which can function as a first-line guidance is of utmost importance. Sensor technology has provided a promising future for the detection of many important diseases through rapid, sensitive and easy applications. Getting high specific and sensitive results by this technology for the detection of biomarkers from blood samples may provide both early and easy detection of cancer without pain with a minimally-invasive technique. Due to the high prevalence of breast, cervical and ovarian cancer in Indian women our aim is to develop a device that can detect cancer at an early stage. A lab-on-a-chip device, which integrates sensors that can detect the above mentioned cancers, will be highly pragmatic due to portability, simplicity of use and affordability. Further this proposed technology can be employed for the mass population screening.
