Researchers have identified fifteen lung-cancer variants, most of them in just the past four years, by decoding DNA in tumors—akin to how crime labs analyze DNA to genetically fingerprint suspects.
The newfound variants have led major cancer centers to revamp their approach to treating cancer and have spurred a rush among drug companies to find medicines that narrowly target each one. The drugs don’t cure cancer and face significant hurdles. But doctors now talk of a “precision medicine” approach in which those pinpoint drugs can treat tumors far more effectively than catchall chemotherapy.
