Scientists said their findings, published in the journal Annals of Oncology, show that the test accurately detects cancer often before any signs or symptoms appear, while having a very low false positive rate. The test, developed by US-based company Grail, looks for chemical changes in fragments of genetic code – cell-free DNA (cfDNA) – that leak from tumours into the bloodstream. The Guardian first reported on the test last year and how it had been developed using a machine learning algorithm – a type of artificial intelligence. It works by examining the DNA that is shed by tumours and...

Scientists can use genetic “weather forecasting” to predict how long it will take for bowel cancer to evolve resistance to a drug before a patient has even started treatment, a new study suggests. Using similar principles to those used in meteorology to predict which mutations might arise, and how they would undergo selection, researchers made long-range forecasts of how cancers might evolve drug resistance. Knowing when drugs are likely to stop working could give clinicians more time to prepare for the next step in a person’s treatment, and to consider offering them alternative therapi...
