For a while, scientists have been basing their cancer research on the idea that a single cell accumulated gene mutations and develops into a malignant tumor. However, this article in The New York Times says that "cancer appears to be even more willful and calculating than previously imagined." Researchers are now studying microRNAs interfere with communication signals between cells and how the microbiome — all those microbes that live in and on the body — can influence how host cells act. "The enemy inside us is every bit as formidable as imagined invaders from beyond. Learning to outwit it is leading science deep into the universe of the living cell," the Times says.
