Screenings Prevent 550,000 Colon Cancer Cases, Report Says
(Undated) -- Screenings for colon cancer have prevented more than half a million cases of the disease, a new report says. Researchers at the Yale Cancer Center studied rates of colorectal cancer and screenings from 1976 to 2009. They found that as screenings went up, cancer cases went down dramatically. They concluded that screenings prevented 550-thousand cancer cases during that 33-year time frame. The study was published Wednesday in the journal "Cancer."
