A study of Medicaid patients showed that those who received fecal immunochemical tests (FIT) in the mail were more likely to complete colorectal cancer screening than those who were just reminded. Colorectal cancer is more treatable if caught early, but only about 63% of the population is screened, and the rate drops further among vulnerable and lower-income patients, said Alison Brenner, PhD, MPH, of the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill.
