Raman spectroscopic Characterization of tissue and Urine of oral premalignant and Malignant conditions

Abstract

Globally cancer is one among the leading causes of morbidity and newlinemortality worldwide with 14 million new cases and 82 million death rates in newlinethe year 2012 In India oral cancer is the most commonly occurring cancer newlineamong men and third most common cancer among women Since majority of newlinethe patients are reporting at the late stages of the disease palliative treatment newlineis only possible and this further adds the already existing high mortality rate newlineThe current screening methodologies followed for cancer detection newlineare highly subjective and invasive This urges a need for an alternative andor newlinea complementary diagnostic modality for realtime objective and noninvasive newlinediagnosis of early cancer In this regard optical based diagnostic newlinetechniques have been emerged for characterization of cells and tissues under newlinevarious pathological conditions and shown potential applications in diagnostic newlineoncology newline newline
