Native fluorescence spectroscopic characterization for diagnosis of cervical cancer

Abstract

Cancer is one of the dreadful diseases and it is a burgeoning health newlineproblem globally It is the second leading cause of death in the world next to newlinecardio vascular diseases The complete treatment of cancer is possible only newlinewhen it is detected at its early stage The life span and also the quality of life newlineare better when the disease is detected and treated early The conventional newlinediagnosis techniques are invasive expensive and some of them are tedious newlineIn this context fluorescence spectroscopy has emerged as a newlinepotential diagnostic tool in particular in the field of diagnostic oncology newlineGenerally the blood characterization using fluorescence spectroscopy can be newlinedone by using both exogenous and endogenous fluorophores The most newlinefrequently used porphyrin derivatives such as dihaematoporphyrin ether newlineDHE and porfimer sodium give rise to characteristic red fluorescence when newlineexcited at the UV or near UV regions newline newline
