“The problem is that many mutations in a cancer cell may be harmless, and targeting them will be a waste of time. And once oncologists narrow down their list to the mutations that actually drive cancer, they have to understand how they do so. Some mutations cause cells to ignore signals to stop growing, for example, while others promote the growth of blood vessels nearby.
“Rather than just typing in a mutation into a search box, doctors have to comb the scientific literature. Not only do they have to read many papers, but they have to evaluate the strength of their conclusions.
