New study reveals why some cells are more susceptible to cancer than others

A hidden clue may explain why some mutated cells become cancerous and others don’t: how fast they divide. A new study from researchers at Sinai Health in Toronto reveals that the total time it takes for a cell to complete one full cycle of division—called the total cell cycle duration, or Tc—can predict whether it will develop into a tumor. Faster-dividing cells are more likely to turn cancerous, while slower ones often escape this fate. This discovery adds a new layer to what scientists know ab
