This book explores the early-stage detection of cancer using polarized
light. It discusses the diverse properties of the light (temporal and
spatial coherence, polarization, fluorescence, etc.) that can be used
non-invasively as an optical technique for recognizing precancerous
lesions, which could become a reliable and accurate method for cancer
screening. The search for the effective means for cancer screening is of
particular interest to scientific and medical communities, because
cancer takes its toll around the globe with no respect for age or
gender. Early detection of the disease is a key factor in increasing the
survival rate and patients' quality of life.
