Starting in 2010, a provision of the health law allowed dependents to stay on their parents’ health insurance until age 26. The number of uninsured young adults fell substantially in the years that followed. The share of 19- to 25-year-olds without health insurance declined to 21 percent in the first quarter of 2014 from 34 percent in 2010 — a decrease of about four million people, federal data show.
Researchers from the American Cancer Society wanted to examine whether the expansion of health insurance among young American women was leading to more early-stage diagnoses. Early diagnosis improves the prospects for survival because treatment is more effective and the chance of remission is higher. It also bolsters women’s chances for preserving their fertility during treatment. And women with health insurance are far more likely to get a screening that can identify cancer early.
