Abstract
Cancer is currently the leading cause of death in countries and an important obstacle to extending national life expectancy. Due to the delayed reporting of results and the delay of patient care caused by the current medical workflow, the result will affect the treatment and prognosis of patients and bring potential economic burden to medical institutions. The development of novel, low-cost, and rapid diagnostic platforms is the key to breaking through the current diagnosis and treatment dilemma. The potential of infrared (IR) spectroscopy as a powerful clinical tool is very clear, as can be seen from countless proof-of-principle studies with high specificity and sensitivity for disease detection and classification. Therefore, for cancer screening, rapid detection, simple operation, low cost, and alternative or auxiliary diagnostic technology infrared spectroscopy has important potential.
