MINIMALLY INVASIVE EARLY SCREENING POSSIBILITIES FOR CANCER USING ATR-FTIR SPECTROSCOPY

Abstract

Cancers affect tens of millions of people worldwide. Despite recent technological advances, screening for many forms of cancer continues to be invasive, time-consuming, and expensive. Additionally, the early stages of cancer are generally asymptomatic, and therefore cancer will often develop unnoticed for years before screening is deemed necessary. Many lives could be saved while cutting treatment expenses by identifying cancers in their early stages. Recent studies show that ATR-FTIR spectroscopy can provide an easily accessible, highly accurate, and cost-effective complement to current screening techniques for cancer. Additionally, ATR-FTIR spectroscopy has the ability to identify various biomarkers which could allow for differentiation between healthy individuals and those with cancer. Consequently, this review examines the existing literature to assess the applicability of ATR-FTIR spectroscopy as a screening technique for cancer and to help guide future research on the topic.
