Some mutations spur rapid growth; others prod nearby blood vessels into sprouting new capillaries; still others send cancer cells out into the bloodstream, where they can seed new tumors. Within 10 years, predicts Robert Weinberg, a cancer biologist at the Whitehead Institute in Cambridge, Mass., "we will analyze the mutant genes and then tailor-make a treatment [for] that particular tumor...
