Raman spectroscopy of breast cancer

Use of spectroscopy for the analysis of biological molecules has significantly increased during the past few years, hence, it is important to accumulate relevant Raman spectroscopic data of breast cancer in one reference document, which will enhance understanding of this field and assist researchers in using Raman spectroscopy to study normal, abnormal, and cancerous breast tissue more precisely and accurately. This article reviews some of the most recent and relevant research work on breast cancer and normal breast tissues analysis using Raman spectroscopy. This review summarizes the differences in frequencies of spectral peak assignments associated with normal and cancerous breast tissues. The aim of this study is to provide an analytical and detailed review including the use of Raman spectroscopy as a tool capable of diagnosis and monitoring of the progression of disease, identifying the chemical pathway of breast cancer, and biomarker identification.
