Diagnostic Application of Fluorescence Spectroscopy in Oncology Field: Hopes and Challenges

Cancer is one of the big killers of world population. The majority of cancers are diagnosed at a late stage, making a cure almost impossible. Fluorescence spectroscopy is an emerging diagnostic tool for various medical diseases including premalignant and malignant lesions. Fluorescence spectroscopy is a noninvasive technique and has been applied successfully for the diagnosis of multisystem cancers with high sensitivity and specificity. Fluorescence spectroscopy minimizes the need for repetitive biopsy, which is routine practice for cancer patient follow-up. But there are many aspects of this new diagnostic technique that should be discussed in future research to overcome limitations and challenges faced by this technique for diagnosis of cancers.
