Catching cancer at its earliest stages saves lives. But in a body made up of trillions of cells, how do you spot a small group of rogue cancer cells? Biomedical researcher Hani Goodarzi discusses his lab’s discovery of a new class of RNAs that, when paired with emerging AI tools, could help detect cancer earlier, more precisely and even through routine blood work — potentially transforming our understanding of the disease.
