“Early detection is a key step to reducing cancer mortality, and our findings suggest that Medicaid expansion under the ACA led to more and earlier cancer detection,” said the study’s corresponding author, Aparna Soni, a doctoral candidate in business economics and public policy in the IU Kelley School of Business.

Previous research by Soni and Simon, the Class of 1948 Herman B Wells Endowed Professor at SPEA, found that the Affordable Care Act increased insurance coverage among people already diagnosed with cancer.

Other co-authors of “Effect of Medicaid Expansions of 2014 on Overall and Early-Stage Cancer Diagnoses” were Lindsay Sabik, associate professor in health policy and management at the University of Pittsburgh; and John Cawley, professor of policy analysis and management and of economics at Cornell University.

In their study, researchers looked at cancer registry data from 2010 through 2014 to estimate post-ACA changes in county-level cancer diagnosis rates, both overall and by stages, in states that expanded Medicaid in 2014 versus those that did not. Medicaid expansion led to an increase of 15.4 early-stage diagnoses per 100,000 people, or 6.4 percent, from pre-ACA levels.

There was no detectable impact on late-stage diagnoses. The overall cancer diagnosis rate increased by 3.4 percent in Medicaid expansion states, compared with non-expansion states.

“These data indicate increases in health coverage lead to increased early detection, which raises the overall diagnosis rate,” Simon said. “Medical research already shows that early cancer diagnosis is important for increasing the probability of successful treatment, reducing mortality, and controlling costs. However, Medicaid expansion appears to have no effect on the diagnosis of late-stage cancers.”

Using information about patients’ age, tumor location, and whether the cancer could be screened for, the researchers found that the increase in early-stage diagnoses was largely seen among those age 35 to 54 and with cancers that are easiest to detect.

“The fact that the increase in early-stage diagnoses was concentrated in cancers amenable to screening is consistent with the increase resulting from the expansion of health insurance and access to care,” the researchers wrote in the paper.

The increase in overall diagnoses was largely driven by increases among those age 45 to 54 and among those with prostate cancer.

There is this trend of what we call the whack-amole game of replacing one molecule with another which is very similar.

I don’t think climate change is going to be this gradual kind of thing. It’s going to be punctuated: You have a hurricane like Matthew. And then you get another one like Irma a year later. And maybe you get a third one in the next two years. Then, you’re going to start seeing effects.

The guns are part of their identity, part of their self- worth, how they protect [themselves], what helps to define [them] as individuals, keeps them safe from the bad guys. It’s the idealization of the American myth of the minutemen and gunslinger of the Wild West.

We tend to tag the provision of basic public services such as water and electricity as technical challenges. This means we look primarily at engineering innovation, price reforms, or privatization to resolve these problems. . . . But technical solutions alone don’t always solve problems, because politics — at the local level and nationally — also shapes service delivery.
