Raman spectroscopy for optical diagnosis in normal and cancerous tissue of the nasopharynx-preliminary findings.

Background And Objectives: Raman spectroscopy (RS), which can detect molecular changes associated with cancer, was explored as a means of distinguishing normal and cancerous nasopharyngeal tissue.

Study Design/patients And Methods: Tissue from six patients with normal and cancerous biopsies was studied using a rapid acquisition Raman spectrometer.

Results: Spectra were obtainable within 5 seconds.
