The U.S. has reached a medical milestone — counting 1 million organ transplants since the first success back in 1954. Advocates marked Friday’s announcement with a new campaign to speed the next million by encouraging more donations. The news comes as the nation’s transplant system is at a crossroads. More people than ever are getting new organs every year. But more than 100,000 others are awaiting their turn, and critics point to policies and errors that waste organs and cost lives. Changes are underway including steps to improve fair access to kidney transplants.
