Scientists just made a wild breakthrough: they’ve built a tiny diamond-based sensor that helps doctors spot if cancer has spread—without using radioactive stuff or allergy-triggering dyes. This handheld device tracks magnetic particles injected into the body, making it way safer and easier to check lymph nodes during surgery. Plus, it’s small enough for keyhole procedures! Could diamonds be a cancer-fighting BFF? #Health #BodyHealth #CancerResearch
