Jorge Soto, a cancer technologist, tells the story of his own family struggles with cancer. He is developing a simple, noninvasive and  open-source test that looks for early signs of cancer. Soto explains that often the determination between life and death with cancer is ‘how early it is caught?’ The test is available on a mobile platform making it not only innovative but,  accessible. At the end of the TED Talk, Soto debuts his working prototype for the first time.
