Cancer screenings have saved the U.S. at least $6.5 trillion, study estimates

Americans have gotten at least 12 million more years of life to live because of preventive cancer screenings they’ve gotten the past 25 years, a new study estimates. That adds up to at least $6.5 trillion in added economic impact, because of scans and tests that look for early signs of breast, colon, cervical and lung cancer in adults at the highest risk.
