Patients paying $3 billion for wasted cancer drugs

Drug companies in the U.S. distribute intravenous cancer drugs in single vials that contain more medicine than many patients will need. The leftover drug is often thrown away, creating a multi-billion dollar waste. This year alone, a projected $3 billion will be wasted on leftover cancer drugs that are simply being thrown away, a new study by Memorial Sloan Kettering Cancer Center concluded.
