Follow the Monongahela River southeast from Pittsburgh to Braddock, Pennsylvania, a steel town whose residents forged America—and paid for it with their lives. The city and its surrounding area have one of the highest cancer rates in the country, and a history of health outcomes split along color lines. Braddock (population: less than 2,000) is also home to people who are determined to stick around and improve their lives and the lives of their neighbors.
