Blood test using light technology to detect cancer early

Researchers are developing a new blood test that uses a technology called Raman spectroscopy — which analyzes how light bounces off molecules in your blood — combined with artificial intelligence to detect cancer early. The study will compare blood samples from healthy people, people with cancer, and people with precancerous conditions to teach the AI system to recognize patterns that signal disease. The goal is to create a simple, non-invasive tool that could catch cancer before symptoms appear.

Early detection of cancer saves lives, but current screening methods are often invasive, expensive, or miss early signs. This trial aims to develop a faster, simpler blood test that could identify multiple types of cancer at once using advanced technology.
