Money Down the Drain?

Premium

In New York City, the Brain Tumor Foundation has been offering free MRIs of the brain, reports The Wall Street Journal's Katherine Hobson. And as The New York Times notes, the Foundation has received almost $2 million from the New York City Council since 2005 in order to continue these screens. But is it wasted money? There is no medical evidence that shows that screening the brains of healthy, asymptomatic people does anything useful, Hobson says. And there is a "growing awareness" that more screening isn't always a good thing, she adds. While there's certainly nothing wrong with trying to find cancer early, screening can pick up anomalies that would never amount to anything and could mean patients end up being treated unnecessarily, and subjected to dangerous side effects of these treatments for no good reason. Neither the American Cancer Society nor the US Preventive Service Task Force recommend screening healthy people for brain tumors, Hobson says.
