...task force's second data set comes from computer-modeled predictions of breast-cancer incidence and death rates based on various screening scenarios. The models were run by researchers at the National Cancer Institute (NCI), who compiled data from six cancer centers around the country, and plugged it into 20 separate age- and time-based screening protocols - from screening women ages 49 to 69 every year and every two years, for example, to screening only women ages 60 to 69 every year and every two years as well.
