 It says an alarming U.S. study. That's right. You can avoid cancer. I don't know if I'd want to go with a brain chip considering this study, but four in ten cancer cases in half of all adult cancer deaths in the United States could be avoided, according to new research. Researchers say their findings demonstrate an urgent need for more effective interventions and access to preventative health care. Roughly 1.8 million new cancer cases are diagnosed in the U.S. every year with roughly 600,000 deaths.
