Accidents are killing more Americans each year, increasingly from overdoses and falls. A new report from the National Safety Council said that in 2014, more than 136,000 Americans died accidentally. That’s up 4.2 percent from the year before and a jump of 15.5 percent over a decade. And the accident rate has risen despite a 22 percent plunge in car crash deaths since 2005. Overdose and accidental poisonings are up 78 percent over a decade — pushing aside car crashes as the No. 1 accidental killer in the U.S. (Borenstein, 6/9)

Sharon Belvin's nightmare with cancer began in 2004, when she was just 22. Belvin was an avid runner, but said she suddenly found she couldn't climb the stairs without "a lot of difficulty breathing." Eventually, after months of fruitless treatments for lung ailments like bronchitis, she was diagnosed with melanoma — a very serious skin cancer. It had already spread to her lungs, and the prognosis was grim. She had about a 50-50 chance of surviving the next six months. (Davis and Palca, 6/9)
