But as scientists have learned more about how tumors grow and spread, the road from cancer screening to saving lives has taken unexpected twists and turns. Some cancers spread to other parts of the body while still small. Others are so aggressive that finding them early doesn’t change the outcome. And still others might never need to be found, or treated, at all.
