Seeing the Invisible: How Polarized Light Contributes to Our Understanding and Detection of Cancer

Light is something we encounter every day, so familiar that it rarely inspires a second thought. Yet beneath its apparent simplicity lies a remarkable complexity. Light can carry information in its brightness and color, but also in its polarization and phase, subtle properties that describe how its waves oscillate and interact. For decades, these hidden dimensions of light have remained largely untapped in medicine. Now, a growing body of research is beginning to reveal their extraordinary potential.
