The video: Breast cancer affects as many as 1 in 8 women, and screening methods aren't nearly as effective as they could be. That's because mammograms, which hunt for tumors using high-tech imaging, are often ineffective for women under 40, due to their denser, more difficult to scan breast tissue. A new sports bra developed by First Warning Systems could change all of that — while also slashing the number of false positives that traditional mammograms serve up. The sports bra uses a sophisticated array of sensors to measure and monitor tiny changes in body temperature caused by blood vessel growth that's associated with the creation of tumors. (Watch a demonstration below.) In preliminary trials, the smart bra — which costs less than $1,000 — detected cancer up to six years before a tumor was even visible, giving doctors a better shot at treating the disease before it develops into something more deadly.

The reaction: What a godsend, says Deanna Pogoreic at MedCityNews. Hundreds of thousands of American women are diagnosed with invasive breast cancer every year, and this "inconspicuous device" could catch tumors before women even see a doctor. "Welcome to the 21st century." It's true, says Andrew Liszewski at Gizmodo. "Cancer is easier to defeat the earlier it's detected," and getting super-frequent mammograms when you're young isn't just impractical, it's prohibitively expensive. The First Warning System bra "has the potential to revolutionize screenings" forever. Take a look:
