Caption: Even in a healthy people, stem cells in the blood accumulate hundreds of mutations. When a cancer-initiating event occurs in one of these stem cells, it captures the genetic history of that cell, including the earlier mutations, and drives leukemia to develop. A schematic of that evolution is pictured above.
