'Fingerprints of cancer' found with infrared light

Summary

Nutrition label

91% Informative

New blood tests are being developed to help diagnose a plethora of cancers, including those of the pancreas, breast and stomach.

The new test is powered by artificial intelligence ( AI ) and examines differences in molecules found in blood plasma.

When blood samples are exposed to flashes of infrared light from a laser, molecules vibrate and absorb energy from the light pulses.

Different components of the molecules absorb or reflect the energy from light pulses, and they emit their own distinctive pattern of light that can be recorded and read as an "infrared molecular fingerprint".
