When it comes to understanding the scope of your health and well-being, there’s no such thing as too much information, according to Andrew Lacy, founder and CEO of Prenuvo . He’s in the business of biometrics, after all: Prenuvo offers full-body MRI scans designed to detect early markers of diseases such as cancer and aneurysms. During a panel discussion Tuesday at Fortune ’s Brainstorm Health conference in Dana Point, Calif.

, Lacy argued against the concept of data overwhelm. “The average person has literally no information about their health,” he said, which is where preventive medicine comes into play. “The challenge that we face as a health system is that we are taught that we are normal—until we all of a sudden are diagnosed with advanced disease, whether that’s cancer or a chronic health condition,” he said.

“Our health declines pretty precipitously at that point, and then we’re spending an awful lot of money trying to keep us alive with poor health.” But ailments like cancer don’t appear overnight, Lacy stressed. They fester over time, too often unbeknownst to their hosts.

But it doesn’t have to be that way. “The starting point here should be providing folks with a comprehensive look inside, and it’s only through that that we can actually understand what it is that we can do as individuals to improve our healthspan and lifespan ,” he said. “I don’t think we’re close to a problem of too much data, if I’m being totally honest.
