Chances are, you know someone who has dealt with, or been affected by breast cancer. According to breast cancer.org, one in every eight women in the U.S. will develop invasive breast cancer at some point in their lifetime. That happened to Julian Rois Cantu’s mother when he was 13. She spent years battling the disease and undergoing treatments, which ultimately led to a double mastectomy. So Julian set out to invent a product that would give the world a better way to detect the early signs of breast cancer. At 17, he developed what’s called “EVA”. It’s a pretty cool invention and you can read more about how it actually works here. Basically it’s a bra that women wear once a week for an hour. Just like a Fitbit or smart watch, EVA uses Bluetooth to send the collected data to a computer or app for evaluation.
