A Review of Spectroscopic and Non-Spectroscopic Techniques for Diagnosing Breast Cancer

Abstract: Malignancy is one of the consequent driving explanations behind death worldwide, and it is assessed at 9.6 million in 2018. Around 1 out of 6 deaths are the direct result of the malignancy. Clinicians state, that age and breast density are two natural elements resulting in the danger of cancer. The mortality rate brought about by malignant growth in low and focus pay countries is, for the most part, around 70%. Imaging techniques play a vital role in detection, staging, and help in guiding treatment decisions. This review paper presents a comprehensive survey involving a literature study about the evolution and efficacy of various breast cancer detection techniques. This work studies the various procedures of imaging techniques mammograms, ultrasound, MRI, PET, CT, Terahertz Spectroscopy, Raman Spectroscopy, Optical coherence Tomography, Mass spectroscopy, diffuse reflectance spectroscopy and Infrared Thermography. Since cancer is a complicated illness with diverse pathophysiology, numerous modifications of the fundamental detection approach employed in each of these modalities have been performed throughout the years to increase the detection efficiency. This paper covers basic preliminary result with FFPE breast cancer blocks of malignant and normal subjects using THz Techniques that lay as a proof of a concept to carry out further research.
