Obamacare led to better cancer outcomes: studies

A pair of studies have found that Obamacare led to an increase in early-stage ovarian cancer detections and helped nearly erase racial differences in the timely treatment of a range of cancers.

The findings, which were presented at the American Society of Clinical Oncology annual meeting in Chicago, come as the administration of President Donald Trump is renewing its efforts to strike down the Affordable Care Act signed into law by his predecessor Barack Obama.

The study on ovarian cancer screening was led by Anna Jo Smith at the Johns Hopkins Department of Gynecology and Obstetrics in Baltimore.

"Having health insurance plays a major role in whether or not a woman has access to care providers who can monitor symptoms and act on those symptoms if necessary,"she said.

The five-year survival rate for women diagnosed with early-stage ovarian cancer is 75 per cent, but the figure drops dramatically to 30 per cent for those diagnosed at a later stage.

The ACA was signed into law on March 2010, and by 2016-17, some 12.7 million people were covered under the law.

The percentage of Americans who were uninsured dropped from 16 per cent in 2010 to less than 12 per cent by 2016.

The researchers used data from the National Cancer Database to look at the years before (2004-2009) and after (2011-2014) the passing of the ACA.

They looked at the stage of the diagnosis and the time to treatment for the 21 to 64 age group, and compared it to those 65 and older, which was used as a control group because they had access to publicly funded Medicare before and after.

They found that there was a relative gain of 1.7 per cent in early-stage diagnosis and a 1.6 per cent improvement in receiving treatment within 30 days.

The team wrote in a statement: "While a 1.7% difference in being diagnosed earlier may not sound very large, for the 22,000 women diagnosed with ovarian cancer in the United States annually, it means that close to 400 more women could be diagnosed at an early, treatable stage."
