A new study in JAMA Internal Medicine published Monday looked at data from 16 million women in 547 U.S. counties in 2000. More than 53,000 were diagnosed with breast cancer that year. As expected, the researchers found that the number of breast cancer diagnoses rose with more aggressive screenings. The surprise: the number of deaths remained the same.
