MediSens+ Cancer is a smart ultrasensitive biosensor for cancer screening. Cancer screening tests aim to detect cancer disease at the early stage, before it causes serious symptoms for which it may be easier to treat successfully. The biosensor has a significant impact at academic, business, and public levels. It reduces the cost of hospitalization, treatment, insurance and increases the patient lifetime and diagnosis precision. In addition, it can improve the quality of life and decrease the treatment time due to early stage diagnosis of non-advanced disease. The biosensor can improve user-friendly self-examination besides being integrated with smart Android/IOS applications which broadens the horizons of theranostics.
